Package: apache
Version: 1.3.29.0.2-4
Severity: normal
Upon starting apache, both the init script and apachectl will report
successfully starting the server. However, none have started. If I
strace -f apachectl start, it turns out that the server is segfaulting.
stat64("/dev/urandom", {st_mode=S_IFCHR|0666, st_rdev=makedev(1, 9),
...}) = 0
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
Process 11374 detached
There was a bug where someone else encountered a SEGV (#230539) caused
by recursively including the config files. I purged all of my config
files and clean installed the package, and the problem persists.
I have had this problem occur for the past few months, and it has
happened on 2.4.21-xfs and 2.4.23-xfs.
Thanks,
David

It is a well known problem that goes way down to libc6. A temporary
workaround is to install libapache-mod-ssl and load it. There is no need
to configure it.
I am closing this bug since all the maintainers from php4 down to libc6
are aware and working actively on this problem. You can check the progress
directly from the BTS on the php4 page.
