Does any of this information help? I see that there are now
others reporting this bug, so perhaps it can be combined with
those.

Well, I got pretty close to getting a backtrace, but ran
across what appears to be a bug in gdb. Either that, or
I am just not finding the proper documentation.
I can get a gdb attached to the proper thread, via:
/usr/sbin/apache.dbg
gdb /usr/sbin/apache.dbg
(gdb) attach <pid>
(gdb) continue
but when
I "continue" it, it gives me a message like "Cannot find
thread 2049: invalid thread handle".
Now, I may be doing something wrong, but I sure can't
tell what.

Incidentally, I have tried every which way to get a core dump,
but even after running apache on port 1025 as a non-root
user, and checking permissions on the CoreDumpDirectory, no
core file is created.
So, I tried attaching gdb to specific processes, but for some
reason, when I attach gdb to a particular process, the process no
longer accepts
connections. Any hints?

Having trouble getting apache to listen to a port when
run under gdb. Will keep trying.
Can't seem to get a core file any other way.
