Zabbix server don't accept items

[pasqu]

Hi all, I use Zabbix 1.4.4 and sometimes server don't accept my value via zabbix_sender, after a simple restart of the server process all return to work.
I the server log I don't see anything

s-zabbix bin # /usr/bin/zabbix_sender -z localhost -s s-zabbix -k PingSF2 -o 1
sent: 0; failed: 1; total: 1

s-zabbix bin # /etc/init.d/zabbix-server stop
* Stopping Zabbix server ... [ ok ]
s-zabbix bin # /etc/init.d/zabbix-server stop
* WARNING: zabbix-server has not yet been started.
s-zabbix bin # /etc/init.d/zabbix-server start
* Starting Zabbix server ... [ ok ]
s-zabbix bin # /usr/bin/zabbix_sender -z localhost -s s-zabbix -k PingSF2 -o 1
sent: 1; failed: 0; total: 1


Anyone can help me?

Thanks Enrico.

you can make zabbix_sender more verbose and also check the zabbix_server.log for errors (set it to level 4 or 5).
Please try to reproduce the problem and post the verbose output of zabbix_sender and zabbix_server.log part of the error.

After about one day the problem remerge. I have set the zabbix server log to 4 (max) and I don't see anything.
Verbose sender say:
zabbix_sender [27350]: Warning: Timeout while executing operation

suggestion?

I have seen this happen when you have too many events being sent in and your trappers are too low (can be configured in your /etc/zabbix/zabbix_server.conf file).

This may not be the problem if you are only sending a few events in (where as I was sending many at a time with only 5 trappers).


If you are not sending a lot of data via the zabbix_sender then I am not sure what might be the problem. How is load on the system? Is MySQL or Zabbix using a lot of processing/memory? Do other things, like agents, still report correctly? Will this happen everytime you run zabbix_sender?

The more details you can provide the easier it will be to figure out

Have fun!

Hi,

I`m have the same error and the scenario is:

- shell script takes data, proccess and send (whith zabbix_sender) to server;
- the script colect and send ~350 itens;
- we put a 'sleep' (0,1 or 2 seconds) between each send;
- in 'zabbix_server.conf' :
===
# Number of pre-forked instances of trappers
# Default value is 5
# This parameter must be between 0 and 255
StartTrappers=60
===
- in log file (debug) we dont identify any thing related whith trapper;

I'm using oracle in backend.
