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. rainer --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx
