IC86590: INCREMENTAL BACKUP HANGS DUE TO A DEADLOCK IN HSM PLUGIN

APAR status

• Closed as program error.

Error description

• Incremental backup hangs when saving large disk managed by
  Windows HSM client.
  This happens because some migrated files need to be retrieved
  during the backup but there is a synchronization problem in the
  HSM plugin and that leads to a deadlock.
  
  Affected Products:
  Tivoli Storage Manager HSM for Windows version: 6.4.0.0,
  6.3.0.0 - 6.3.0.1 (inclusive), 6.1.0.0 - 6.1.5.1 (inclusive),
  the corresponding IBM Tivoli Storage Manager for Windows
  Backup-Archive Client versions are 6.1, 6.2 and 6.3.
  
  Customer/L2 Diagnostics :
  
  In actlog the session timeout :
     ANR0481W Session xxxx for node NODENAME (WinNT)
          terminated - client did not respond within 6000 seconds.
  
  In one of the HSM client  logs ( dsmc.log, dsmagent.log
  dsmcsvc.log )  , the following message may be seen
  
  DSMC (4188:26D0) connectToFileSpace
  12-05-21 17:50:52.270
   E: INTERNAL: Not in critical setion: '0x0300005e (E:
