semaphores

Post by penny »

I've written about 'Could not obtain semaphore' errors, and your response has been to use ipcrm to remove them.

The problem is that the only thing running on this server is webinator (2.56 commercial) and apache. Since our other sun systems running apache do not have any problems with semaphores, it seems like the semaphores are being left by webinator.

The frequency has increased to about 3 times a week, and when it happens our search fails. It has become a problem that may force us to abandon webinator.

Is there any tuning or anything I can do to make sure semaphores are removed when webinator is done with them? Is any research being done on your end to fix this?

Thank you.

There should only be one semaphore created per database (not per executed program) . The issue may be permission related. You might wish to ensure that all the programs are running suid to the same user.
