Every time I have seen something like this it is a corrupt file in the file system. Run CHKDSK.

Anybody ever seen this one? Scheduler appears to back up C drive ok, then just locks up sometime during the backup of D: dsmsched.log: 02/25/2002 03:01:48 ANS1898I ***** Processed 73,000 files ***** 02/25/2002 03:01:51 ANS1898I ***** Processed 73,500 files ***** 02/25/2002 03:01:54 ANS1898I ***** Processed 74,000 files ***** 02/25/2002 03:01:58 ANS1898I ***** Processed 74,500 files ***** 02/25/2002 03:02:01 ANS1898I ***** Processed 75,000 files ***** 02/25/2002 03:02:05 ANS1898I ***** Processed 75,500 files ***** 02/25/2002 03:02:09 ANS1898I ***** Processed 76,000 files ***** (nothing further) Messages in dsmerror.log: 02/25/2002 02:54:10 ANS1802E Incremental backup of '\\slbmpst4\c$' finished with 11 failure 02/25/2002 03:02:11 Mutex lock failed: 6. 02/25/2002 03:02:11 Release mutex failed; reason 6. 02/25/2002 03:02:12 Mutex lock failed: 6. 02/25/2002 03:02:12 Release mutex failed; reason 6. 02/25/2002 03:02:13 Mutex lock failed: 6. etc. . These "Mutex" errors continued for hours until the scheduler was stopped. Any idea what causes this? Hasn't recurred since the scheduler was restarted. This is WinNT 4.0, SP 6 Client is 4.2.0.0 Thanks.
