Topic: Problem with mod_mem_cache 2.2.11

[DanMan]

Hi Guys

Every now and again I get the following error reported for Apache in the event log:

Faulting application httpd.exe, version 2.2.11.0, faulting module
mod_mem_cache.so, version 2.2.11.0, fault address 0x00001804.

At times it is posted every 12 seconds for about 30 minues, then seems to sort itself out. Other times when I manually restart Apache it is sorted.

Users cannot reach Apache while this is happening.

I run on an up to date Windows 2003 - with only about 50% memory usage and very low cpu usage.

I would appreciate any suggestions you might have in finding my problem. None of my test machines have a problem - but they of course don't run under the same load as my production machine.

Config for mod_mem_cache is:

LoadModule mem_cache_module modules/mod_mem_cache.so
<IfModule mod_mem_cache.c>
CacheEnable mem /
MCacheSize 4096
MCacheMaxObjectCount 100
MCacheMinObjectSize 1
MCacheMaxObjectSize 2048
CacheDisable http://security.update.server/update-list/
</IfModule>

The error log does not seem to tell me much, but here is what is logged around one of the problems:

AFAIK there is an issue in the memcache which is fixed in 2.2.12 which should be released soon.

[DanMan]

Cool. Anxiously awaiting it then.
