    Does anyone have any further suggestions as to what might be the underlying cause of the issue?

        I'm pretty sure the memory utilization issues are a bug in either PHP 7.2 or in Red Hat's build of PHP 7.2. It could also be in one of the libraries that FPM links with.

        Beyond tuning pm.max_requests = 100, as you have, the next thing I would suggest is what I said in an earlier post: you probably don't need 35 spare servers for the Zabbix front end. pm.max_spare_servers should be an integer multiple of pm.min_spare_servers, so try setting pm.max_spare_servers = 10 and restart your worker pool.

        As I mentioned earlier, if you want a little bit of visibility into the usage of that worker pool, it's also possible to enable a status URL for the pool, so you can see how many workers you've had active (max) at one time, what each worker is doing, etc.

            Hi Tim,

            Thanks for the reply and suggestions.

            I have amended the zabbix.conf file as suggested and will restart the entire Zabbix service as I do not know how to restart the worker pool.

            cat /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf
            ;THIS FILE IS MANAGED BY PUPPET
            [zabbix]
            user = apache
            group = apache

            listen = /var/opt/rh/rh-php72/run/php-fpm/zabbix.sock
            listen.acl_users = apache
            listen.allowed_clients = 127.0.0.1

            pm = ondemand
            pm.max_children = 10
            pm.start_servers = 5
            pm.min_spare_servers = 5
            pm.max_spare_servers = 10
            pm.max_requests = 100
            pm.max_servers = 10
            php_value[session.save_handler] = files
            php_value[session.save_path] = /var/opt/rh/rh-php72/lib/php/session/

            php_value[max_execution_time] = 30
            php_value[memory_limit] = 64M
            php_value[post_max_size] = 16M
            php_value[upload_max_filesize] = 2M
            php_value[max_input_time] = 30
            php_value[always_populate_raw_post_data] = -1
            php_value[max_input_vars] = 10000
            ;Set correct timezone
            php_value[date.timezone] = Europe/London

            Also, the php-fpm service doesnt look particularly healthy either, is this normal and expected or could this have something to do with the issue?

                Both in this post and your previous one you show a PHP-FPM pool configuration file that references "rh-php72" in a couple places, which immediately made me assume you were using Red Hat (or derivative) software collection library (SCL) rh-php72 components.

                However, now that you show your output from "systemctl status", something is very strange. If you're using the php-fpm that comes with SCL rh-php72, the service name is not 'php-fpm', it's 'rh-php72-php-fpm.service'. It's like you're mixing two different versions of PHP-FPM on the system. Did you try Remi's PHP install at one point?

                On my RHEL 7.x server where the Zabbix front-end is currently running:

                Code:
                $ sudo systemctl list-units | egrep php

                (Note: we call our php-fpm worker pool "www" rather than "zabbix", to match other PHP apps in our environment, but this is showing the worker pool for the Zabbix front-end).

                Can you clarify how you got to the point of having some config from SCL rh-php72 and some config that clearly isn't from SCL?

                    Hi Tim,

                    Thanks for taking the time to reply and sharing your observations.

                    I am very new to Zabbix so please bear with me.

                    We do indeed have a 'rh-php72-php-fpm.service' so I guess I was looking at the wrong service - sorry. I will also ensure that the redundant php-fpm service is removed from systemd to avoid any future misunderstandings.

                    Code:
                    systemctl status rh-php72-php-fpm.service

                    If I look at the conf file...

                    cat /etc/opt/rh/rh-php72/php-fpm.conf
                    Code:
                    ;;;;;;;;;;;;;;;;;;;;;
; FPM Configuration ;
;;;;;;;;;;;;;;;;;;;;;

; All relative paths in this configuration file are relative to PHP's install
; prefix.

; Include one or more files. If glob(3) exists, it is used to include a bunch of
; files from a glob(3) pattern. This directive can be used everywhere in the
; file.
include=/etc/opt/rh/rh-php72/php-fpm.d/*.conf

;;;;;;;;;;;;;;;;;;
; Global Options ;
;;;;;;;;;;;;;;;;;;

[global]
; Pid file
; Default Value: none
pid = /var/opt/rh/rh-php72/run/php-fpm/php-fpm.pid

; Error log file
; If it's set to "syslog", log is sent to syslogd instead of being written
; in a local file.
; Default Value: /var/opt/rh/rh-php72/log/php-fpm.log
error_log = /var/opt/rh/rh-php72/log/php-fpm/error.log

; syslog_facility is used to specify what type of program is logging the
; message. This lets syslogd specify that messages from different facilities
; will be handled differently.
; See syslog(3) for possible values (ex daemon equiv LOG_DAEMON)
; Default Value: daemon
;syslog.facility = daemon

; syslog_ident is prepended to every message. If you have multiple FPM
; instances running on the same server, you can change the default value
; which must suit common needs.
; Default Value: php-fpm
;syslog.ident = php-fpm

; Log level
; Possible Values: alert, error, warning, notice, debug
; Default Value: notice
;log_level = notice

; If this number of child processes exit with SIGSEGV or SIGBUS within the time
; interval set by emergency_restart_interval then FPM will restart. A value
; of '0' means 'Off'.
; Default Value: 0
;emergency_restart_threshold = 0

; Interval of time used by emergency_restart_interval to determine when
; a graceful restart will be initiated. This can be useful to work around
; accidental corruptions in an accelerator's shared memory.
; Available Units: s(econds), m(inutes), h(ours), or d(ays)
; Default Unit: seconds
; Default Value: 0
;emergency_restart_interval = 0

; Time limit for child processes to wait for a reaction on signals from master.
; Available units: s(econds), m(inutes), h(ours), or d(ays)
; Default Unit: seconds
; Default Value: 0
;process_control_timeout = 0

; The maximum number of processes FPM will fork. This has been designed to control
; the global number of processes when using dynamic PM within a lot of pools.
; Use it with caution.
; Note: A value of 0 indicates no limit
; Default Value: 0
;process.max = 128

; Specify the nice(2) priority to apply to the master process (only if set)
; The value can vary from -19 (highest priority) to 20 (lowest priority)
; Note: - It will only work if the FPM master process is launched as root
; - The pool process will inherit the master process priority
; unless specified otherwise
; Default Value: no set
;process.priority = -19

; Send FPM to background. Set to 'no' to keep FPM in foreground for debugging.
; Default Value: yes
daemonize = yes

; Set open file descriptor rlimit for the master process.
; Default Value: system defined value
;rlimit_files = 1024

; Set max core size rlimit for the master process.
; Possible Values: 'unlimited' or an integer greater or equal to 0
; Default Value: system defined value
;rlimit_core = 0

; Specify the event mechanism FPM will use. The following is available:
; - select (any POSIX os)
; - poll (any POSIX os)
; - epoll (linux >= 2.5.44)
; Default Value: not set (auto detection)
;events.mechanism = epoll

; When FPM is built with systemd integration, specify the interval,
; in seconds, between health report notification to systemd.
; Set to 0 to disable.
; Available Units: s(econds), m(inutes), h(ours)
; Default Unit: seconds
; Default value: 10
;systemd_interval = 10

;;;;;;;;;;;;;;;;;;;;
; Pool Definitions ;
;;;;;;;;;;;;;;;;;;;;

; Multiple pools of child processes may be started with different listening
; ports and different management options. The name of the pool will be
; used in logs and stats. There is no limitation on the number of pools which
; FPM can handle. Your system will tell you anyway :)

; See /etc/opt/rh/rh-php72/php-fpm.d/*.conf

                        I've restarted the rh-php72-php-fpm.service as I have previously only been restarting the Zabbix service. Im assuming that only restarting the Zabbix service wasnt the correct thing way of implementing the changes to the /etc/opt/rh/rh-php72/php-fpm.conf' so hopefully now we will see an improvement in memory utilisation. I will continue to monitor and update you tomorrow.

                            My problem appears to be resolved following the 'rh-php72-php-fpm.service' restart.

                            Clearly restarting just the Zabbix service was the wrong thing to do.

                            Thanks tim.mooney
