Apache2 Segmentation fault, Help please.

[Ironik]

Hello all,

I'm pretty new to linux and even more so to Gentoo. I'm running an apache server on a box and have been doing a number of configuration changes recently. I am getting an errow now, however, and i'm not sure exactly what the problem is. Can somone please point me in the right direction? Thank you.

ERROR:

/etc/init.d/apache2: line 23: 5477 Segmentation fault $APACHE2 ${APACHE2_OPTS} -t >/dev/null 2>&1
* Apache2 has detected a syntax error in your configuration files:

Also, here's line 23's function

it looks like you have upgraded apache to a newer version and now the syntax in the configuration file wants some work.
or have you maybe just forgotten to run etc-update?

Based on that output, Apache is crashing at startup. The syntax error message is bogus, and is only appearing because Apache is exiting non-zero. What modules are you using in Apache? Are they all up to date? What is the output of emerge --info; emerge -pv apache?

Can you capture a core dump from the server? Read How to get meaningful backtraces in Gentoo before trying to capture the core dump.

i had the same problem. i removed /etc/init.d/apache2 and re-emerged apache. now it works!
