Reply To: Can’t lock semaphore

[Jeff Shields]

We’ve had this problem many times. We’ve found that the only way to get rid of it is to:

– Stop all processes and site daemons

– Copy the $HCISITEDIR/exec folder to something else (e.g. $HCISITEDIR/exec1)

– Delete the $HCISITEDIR/exec folder

– Copy $HCISITEDIR/exec1 back to $HCISITEDIR/exec

– Restart site daemons and processes

Don’t ask me why it works, I’ve no idea, it’s just something I tried one day. Maybe deleting the exec directory gets rid of the broken semaphore links?

Also, check your system semaphore parameters in /etc/system to make sure they are set to the recommended levels.
