Problem zabbix_agentd v1.4.2 on Sparc Solaris 8

[lreger]

I've already successfully installed the previous version 1.4.1
on SunOS 5.8 sparc SUNW,Sun-Fire-V440

I compiled successfully the new version 1.4.2 on this machine but
if I try to start the zabbix_agentd, I get the following error:

zabbix_agentd [12234]: Can not create Semaphore [No space left on device]
zabbix_agentd [12234]: Unable to create mutex for log file

I used exactly the same configuration for v1.4.1 and v1.4.2, I've checked
all devices there is enough space. After I rolled back to v1.4.1 the agentd
started without any problems.

Than I tried to start the new v1.4.2 zabbix_agentd on a different machine
SunOS 5.8 sparc SUNW,Sun-Fire-480R (the patch level on this machine
is older than the patches applied on the other machine), but here the
agentd starts without any problems.

Any idea?

Check per-user limits on IPC resources. I am prettry sure you hit some limit.

[hannibal20]

turn off all zabbix instances, then do:

# ipcs

if you see any resources held by the user which runs usually zabbix's processes, then use

# ipcrm [flag] [id]

to delete the resource. Start your agents afterwards.

[lreger]

I used

# ipcs -A

to find out which shared memory segments are currently used then I removed
some currently allocated but unused segments for the zabbix user (no zabbix process is running):

# ipcrm -S semkey -M shmkey

after that I tried to restart the the new zabbix_agentd v1.4.2 but now I run into another problem which seems to be also the result of a unsuccessfull shmget() system call:

Can't allocate shared memory for collector. [Invalid argument]

have you changed the amount of allocated shared memory size from v1.4.1 to v1.4.2 in the zabbix_agent code?

It may be that some system wide kernel parameters according to shmget
operation have to be changed for the machine. I will check that.

Solaris 8 has a default of 1 MB max allocateable shared memory size, this is
a bit to small for zabbix (2 MB should be work) in Solaris 9 this default value is increased to 8 MB.

I will increase the max shared memory size to 100 MB (Note: this is more than enough)

shmsys:shminfo_shmmax = 104857600

in /etc/system and reboot the system, after that it should work

2MB of shared memory is normally enough for ZABBIX agent. The memory is used to store pre-CPU statistics of up-to 16 CPUs.
