Hi. We're getting a segfault when httpd shuts down
when using mod_perl on Red Hat 6.2, and I'd like to
know whether anyone else has seen this as well. If I
run "httpd -X -f /home/gvwilson/httpd.conf" under gdb,
the stack trace is:

Is this a known issue? If so, I'd be grateful for pointers to a solution.
Thanks,
