I've been having a major problem with my Apache setup for a while. I couldn't find anything about this error on Google, I was hoping someone here might know more. About once or twice every 24 hours, at different times, Apache stops serving requests. The server processes still run normally, but when you try to access a site, nothing happens.
The access log shows little to no activity, and the error log shows the following while the server is down:

critical_release() failed: Invalid argument
critical_acquire() failed: Invalid argument
critical_release() failed: Invalid argument
critical_acquire() failed: Invalid argument
critical_release() failed: Invalid argument

The server can be brought up by killing the process and restarting it (not by issuing a restart command to the process)

and when it comes back up, the error log shows the following:

[Sun Jun 27 19:23:41 2004] [warn] pid file /usr/local/psa/apache/logs/httpd.pid overwritten -- Unclean shutdown of previous A
pache run?

The server then responds properly until the next time it stalls.
Any thoughts?

Thanks in advance,

Patrick
