Bug#293156: apache: segfaults when started, strace shows failure after or during reading file pkg's magic.mime
Hello Adam, An apt-get dist-upgrade did the trick. Be it known that you are the man! Adam Conrad wrote: Adam Conrad said: Also, what version of libc6 do you currently have installed? Nevermind.

Can you try upgrading libc6 (better yet, if you have the bandwidth, update the whole system), and let me know if this bug goes away? Thanks. ...

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!
