I get the same hang here on an NFS server. It's usually at night (when=20 the machine is not heavily loaded). Every 6-7 days. I looked around if I=20 could find a cron job that is running on the server or one of it's=20 clients at the time, but nothing special. The backup (dump to a file on=20 an NFS mount) is usually ready 5-20 minutes before. The same backup runs=20 another day but it always happens either the night from Sat to Sun or=20 the night from Sun to Mon. > KDB: enter: Line break on console > [thread pid 61 tid 100052 ] PID 61, the syncer.
