Has a number of sleeping processes swapped out. >Description: Not usre exactly but the symtoms were: name server (bind8) wasnt responding. Went to investigate. Took ages to get a ssh password prompt. Got in, had a look about. Disk access was normal (not particularly high), plenty of swap space, plenty of disk space, 90% of network bufers were in use. named was running. Tried to su but the su prompt would hang. Used sudo su instead. Looked at a netstat. A number of apparently hung mail connections (big send and receive queues (17K)). I looked at /var/log/messages...nothing had been logged for the past 7 hours (overnight). I tried logger test. Didnt appear in the log file. I tried to kill named to restart it. kill <named pid> didnt work. I tried several times. It was in Ss state. kill -9 worked :-/. I fried named up again... still no go (it ran ok but didnt log anything or work). I killed off the apparently hung smtp sessions. I hupped syslogd. Tried logger again..still didnt work. I killed syslogd and started it again. One of my logger tests appeared in the log file. named startup messages appeared, named started working, su started working...the box appeared to be back to normal. >How-To-Repeat: >Fix: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
