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)... *----> State Dump for Thread Id 0x2988 <----* eax=00000010 ebx=6eec7670 ecx=77bbcefb edx=00000000 esi=07af2200 edi=07af221c eip=6eec767c esp=0efbff28 ebp=71c06eb4 iopl=0 nv up ei pl nz ac pe cy cs=001b ss=0023 ds=0023 es=0023 fs=003b gs=0000 efl=00010213 function: libapr!apr_palloc 6eec766d 90 nop 6eec766e 90 nop 6eec766f 90 nop libapr!apr_palloc: 6eec7670 51 push ecx 6eec7671 8b542408 mov edx,[esp+0x8] 6eec7675 8b44240c mov eax,[esp+0xc] 6eec7679 53 push ebx 6eec767a 55 push ebp 6eec767b 56 push esi FAULT ->6eec767c 8b7228 mov esi,[edx+0x28] ds:0023:00000028=????????
