IC61012: TSM SERVER CRASH IN PKDESTROYCONDITION

IBM Tivoli Storage Manager V6.1 Fix Pack 3 (6.1.3) Server Downloads

APAR status

• Closed as program error.

Error description

• A TSM Library Manager server may crash during handling of
  an idle mountpoint. A small timing window exists such that
  two separate threads access the same idle mountpoint owned by
  a Library client during dismount processing.
  Under such conditions, the TSM library manager crashes.
  
  Customer/L2 Diagnostics
  A TSM library manager running on AIX will show the following
  call stack :
  
  pthread_kill(??, ??) at 0x9000000004886bc
  _p_raise(??) at 0x9000000004880d0
  raise.raise(??) at 0x90000000005a298
  abort() at 0x900000000085dac
  AbortServer() at 0x10000ffe0
  pkAbort(??) at 0x100011814
  TrapSyncError(??) at 0x10000e860
  pkDestroyCondition(??) at 0x10000ea98
  DestroyMp(??) at 0x1002a447c
  PvrFindIdleMp(??, ??, ??, ??, ??) at 0x1002a95b0
  pvrOpen(??, ??, ??, ??, ??, ??, ??, ??) at 0x100251d10
  pvrMgrOpenVol(??, ??, ??, ??, ??, ??, ??, ??) at 0x10024a408
  DoOpenVolume(??, ??) at 0x1002b1564

  SessionThread(??) at 0x100375724
  StartThread(??) at 0x10000fef0
  
  The same core file will show another thread processing
  in WaitForDismount. For example :
  
  pkWaitCondition(0x12979aaa0, 0x124660d98) at 0x10000ecf8
  WaitForDismount(??, ??) at 0x1002a1f0c

  pvrOpen(??, ??, ??, ??, ??, ??, ??, ??) at 0x100251d10
  pvrMgrOpenVol(??, ??, ??, ??, ??, ??, ??, ??) at 0x10024a408
  DoOpenVolume(??, ??) at 0x1002b1564
  SmLibraryServerSession(??) at 0x1002b9b50
  DoLibraryServer(??, ??) at 0x1001a9e00
  smExecuteSession(??, ??, ??, ??, ??, ??, ??, ??) at 0x1001ae520
  SessionThread(??) at 0x100375724
  
  TSM Versions Affected:
  TSM 5.4, 5.5 and 6.1 servers on Unix,Linux and Windows platforms
  This only affects Library Managers servers, not Library Clients.
