Hello, I' m running httpd 2.0.50 on a production system. Every couple of days I receive a crash, the most recent of which is listed below. I believe this is related to allocating memory. I'm unable to upgrade the production Apache to test whether a later version resolves this issue. Also, I'm unable to reproduce the problem outside of the production environment (don't have accurate load tests).
I reviewed the change logs and did not see anything specifically related to this on the 2.0 line after 2.0.50, so I don't see a clear reason to upgrade yet.
I have about 300-600 threads to the webserver at a given time, and I've seen the Apache.exe process report 1GB memory use in Windows tasklist. I'm running Windows Server 2003.
Any ideas on how to resolve the issue? Or any rationale as to why an upgrade would have a
good chance of resolving this type of issue?
The following is from drwatsn32.log and is the section that reports the fault (there is much more to the log but this is the fault section)...
