Zabbix 1.6.4 Agent restart race?

[lamont]

from my zabbix_agentd.log file:

22808:20090409:012851 ZABBIX Agent stopped. ZABBIX 1.6.4.
zabbix_agentd [17966]: DEBUG: ZABBIX semaphores already exist, trying to recreate.
zabbix_agentd [17966]: Semaphore [0] error in semctl(SETVAL)
zabbix_agentd [17966]: Unable to create mutex for log file

that was the result of a simple /etc/rc.d/init.d/zabbix-agent restart which in the logs claimed that startup was successful, but the new agent logged that and apparently died.

do i need to do something like:

/etc/rc.d/init.d/zabbix-agent stop
sleep 2
/etc/rc.d/init.d/zabbix-agent start

instead of just calling restart, so that the semaphores get cleaned up before attempting a start?

Welcome to my world. Though not in my agent log, but in the server log:

/usr/sbin/zabbix_server [24370]: Semaphore [0] error in semctl(SETVAL)
/usr/sbin/zabbix_server [24370]: Unable to create mutex for log file

I've got the same errors, running Zabbix 1.6.4 on FreeBSD 7.1. However, if I start Zabbix as root, rather than under the user "zabbix", all is fine. I haven't done any research into why yet, but will as soon as I get a chance to do so.

Running another server (RHEL 4 & Zabbix 1.6.4), this problem does not exist, even running as a non-privledged user.

Same problem Freebsd 7.1

I have the same problem here

uname -a
FreeBSD ns2.local.local 7.1-RELEASE FreeBSD 7.1-RELEASE #0: Thu Jan 1 14:37:25 UTC 2009 [email protected]:/usr/obj/usr/src/sys/GENERIC i386

When zabbix tries to execute at boot time it doesn't because of the following error
797:20090630:082459 [Z3001] Connection to database 'zabbix_db' failed: [2003] Can't connect to MySQL server on '127.0.0.1' (61)

Then i run it as root directly from console and shows this:
/usr/local/bin/zabbix_server [1173]: Semaphore [0] error in semctl(SETVAL)
/usr/local/bin/zabbix_server [1173]: Unable to create mutex for log file

But if i run it again, the second time it executes without trouble, i have only tried on freebsd 7.1 i386, freebsd 6.4 i386 and 6.2 SPARC, on the 6.4 and 6.2 SPARC i have no trouble at all.

Regards.
