It didn't help. Exactly the same symptom happened again. It looks like it happens a few days after the last system reboot. After it happens the first time, restarting Apache immediately produces one such "stuck" thread - it looks like some system state gets corrupted over time. >> How do I pick what thread to backtrace in gdb? > > i think the command is 'info threads' or 'show > threads' then i think you just type > 'thread FOO' to select the thread. Both commands don't work / don't exist. Any others? (background: apache22-worker port, no mod_php, on 7.0 and 7-STABLE suddenly gets stuck at 100% CPU; the same setup worked on 6-STABLE. I'm looking for ideas) _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
