Bug#293156: apache: segfaults when started, strace shows failure after or during reading file pkg's magic.mime
Package: apache
Version: 1.3.33-3
Severity: important
I noticed that my wesite stopped accepting connections. I have both apache-ssl and apache installed, apache-ssl still works fine. I can't start apache manually with a command like "apache -X" of "apache -F", I just get a Segmentation fault. Turning the LogLevel to debug also shows no errors. Upgrading from apache 1.3.33-2 to 1.3.33-3 didn't help, nor reinstalling the package apache. Checking my RAM and blocks on all filesystems show no problems. Reverting to an original copy of httpd.conf didn't help, which has no VirtualHosts, so I don't think bug 284215 is happening here.
An strace shows interesting output near the end when running the command
"strace apache -X":

The 5th last line looks interesting, perhaps input is expected but there
is none in the empty ""?
I upgraded the "file" and "libmagic1" packages (since
/usr/share/misc/file/magic.mime comes from libmagic1), still no luck. Could
this affect people upgrading to sarge?
My website is down (at least on port 80, SSL access still works) and can't get up, please help!
