Undocumented Error Code

We just went live with FMS last week and I have had many complaints about folk being disconnected midstream. On checking the master log I see the following message repeating muliple times each second, using up a lot of log space too.

2010-09-20      14:18:07        31770   (e)2581394      Failed to wait for process condition: errno(43).

Someone elsewhere mentioned about lack of available arrays or semaphores. Here is what I get from my server.

------ Semaphore Limits --------
max number of arrays = 1024
max semaphores per array = 250
max semaphores system wide = 32000
max ops per semop call = 32
semaphore max value = 32767

kernel.sem = 250        32000   32      1024

Anyone got any suggestions?
