If you get this error, it is often because you have configured Apache with modules that weren't actually installed. Eg. you try to load the PHPmodule but didn't actually install the apache2 php module, so the server can't start. In general, this error can often be caused by issues with problematic modules and/or Apache being configured for modules that have not actually be installed (eg. libapache2-mod-php) is missing. The above results in this less than obv........

This is one in a series of weird things whichIthought was motherboard related (I RMA'd the motherboard), the RAM tests fine with memtest86 and I used badblocks on both RAID 1 members with no errors and smartctl is happy with them. Basically the array crashes the kernel a lot and has issues when writing.

This happened on one of my Ubuntu machines where Igot some kind of segfault on line 21 from LAME at random while encoding MP3s (a second try is fine usually). I've read that it's best to compile it from source and that has solved most issues for people. Here is my preferred configure line: ./configure --enable-mp3x --with-fileio=lame --enable-debug --with-vorbis Even with that I got a different error this tim........
