I am trying to run live Firebird server 2.1.3 on OpenVZ container and I am having all sorts of problems. I have been able to run test database servers on OpenVZ containers with no problems.
I keep getting following messages in the firebird log.

Fatal lock manager error: semaphores are exhausted, errno: 11
When the "semaphores are exhausted" message appears then the database server becomes unresponsive and the container hosting the firebird service has to be restarted. I tried increasing the semaphore count but it does not let me. When I try to up the limit in firebird.log I see error like this:
stagedata-01 Mon Dec 7 08:47:13 2009
Number of requested semaphores (256) is greater then size of the existing semaphore set (128)
Even though the "sysctl kernel.sem" returns
kernel.sem = 256 32000 32 128
I have no idea what to do with "lock conversion denied" errors.
If this is any relevance, I am using a CentOS 5 64 bit with firebird distribution from http://fedoraproject.org/wiki/EPEL repository.
Installed Packages

Any suggestions on how to resolve these issues would be appreciated.
