Error Every Time I Try to Start Zabbix 1.8.1 Server.

[hebersonsette]

Ubuntu 9.10 Server 32 Bit MySQL 5.1.37 Apache 2.2.12

Every time I try to start a Zabbix Server the following messages appears in the /tmp/zabbix_server.log. file

./zabbix_server [1471]: ERROR: Can't recreate Zabbix semaphores for IPC key 0x7a00fdb4 Semaphore ID 65537. Operation not permitted.
./zabbix_server [1478]: ERROR: Can't recreate Zabbix semaphores for IPC key 0x7a00fdb4 Semaphore ID 65537. Operation not permitted.


What can be the root cause for this?

Any help would be appreciated

It sounds like you may have a semaphore limit somewhere.

The two places I would verify are:

/etc/limits.conf

and

sysctl for kernel.shmmax and kernel.shmall

Did it help?

I'd say you're trying to start Zabbix server as root from the zabbix_server binary.
But you're either running it as a zabbix unpriviledged user or using a
/etc/rc.d/init.d/zabbix_server start
equivalent as root right?

If that's the case,
You should start by erasing the semaphores from the old zabbix server with "ipcs -a" and "ipcrm -s semaphoreId" commands.
