[Vincent GRENET]

Hello.   Amanda dumper hangs sometimes; and backup fails with data timeout:   FAILURE AND STRANGE DUMP SUMMARY:   localhost  /home lev 0 FAILED [data timeout] The dumper is still there hours later:   #ps -fu amanda UID        PID  PPID  C STIME TTY          TIME CMD amanda   21555     1  0 00:55 ?        00:00:00 /usr/lib/amanda/sendbackup amanda   21556 21555  0 00:55 ?        00:00:01 dump 0usf 1048576 - /dev/sdb1 amanda   21557 21556  0 00:55 ?        00:00:04 dump 0usf 1048576 - /dev/sdb1 amanda   21558 21557  0 00:55 ?        00:02:36 dump 0usf 1048576 - /dev/sdb1 amanda   21559 21557  0 00:55 ?        00:02:50 dump 0usf 1048576 - /dev/sdb1 amanda   21560 21557  0 00:55 ?        00:02:41 dump 0usf 1048576 - /dev/sdb1 amanda   21894 21367  0 09:47 tty1     00:00:00 -bash amanda   21920 21894  0 09:48 tty1     00:00:00 ps -fu amanda I set dtimeout to 3600s; it hangs whether I use a holding disk or not. When the dump succeeds, it runs for 46 minutes.   My configuration is a RHS 7.1 (amanda 2.4.2p2).   Any ideas ?   tia Vincent
