--- Comment #1 from Wolfram Schneider <[email protected]> --- I googled for similar bug reports and found this: from 2007, for FreeBSD 6.x https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=104406 kern/104406: Processes get stuck in "ufs" state under persistent CPU load https://forums.freebsd.org/threads/9150/ We have a problem with FreeBSD 6.2-STABLE (aw62) #2: Fri Jun 22 02:26:27 MSD 2007 some reports about dirhash tuning: https://forums.freebsd.org/threads/7794/ Try something like procstat -f -w 1 pid_of_httpd or run top -U www -m io to see disk activity. I ran into same, in our case it the solution was dirhashing: sysctl -a | grep dirhash will show you current state, and most likely increasing vfs.ufs.dirhash_maxmem will solve your problems. sysctl -a | grep mem https://wiki.freebsd.org/WaitChannels ufs: Waiting to read from a file or directory on a UFS filesystem that is being written to by another thread, or waiting to write to a local file or directory that is being read or written by another thread https://wiki.freebsd.org/DirhashDynamicMemory https://forums.freebsd.org/threads/34023/ Since vfs.ufs.dirhash_lowmemcount is already at 25, you should consider increase vfs.ufs.dirhash_maxmem. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
