Lots of options, more information needed. If it's an issue that slowly
eats up your worker threads, monitoring the server-status page with
ExtendedStatus On may provide good hints. Otherwise, wait until it
stops responding and try to check with strace if anything suspicious
is going on. Finally, check
"thread apply all bt" in a gdb session attached to some of the blocked
processes, possibly a few times with cont and Ctrl+C inbetween to see
where it's really waiting. You may need to re-build with debug info,
and/or install the debug info for all libraries your httpd is linked
against.
