IC86542: SERVER CAN CRASH IN NASAN_FETCH

IBM Tivoli Storage Manager V5.5 Fix Pack 7 (5.5.7.000) Server Downloads

APAR status

• Closed as program error.

Error description

• More then one SAN Inquiry requested are running at the same
  time.  This can be seen if more then one Query SAN is done.
  In the reported case, the ODBC client was collecting the Actlog
  information and the Admin Center was doing normal select queries
  at the same time.
  
  Tivoli Storage Manager Versions Affected:  All supported levels
  
  Customer/L2 Diagnostics:
  The Actlog may have many messages before the crash like:
  ANR2017I Administrator ADMIN issued command: FETCH NEXT 50
  This is does not have to be the case as the cause was due to the
  TSM SAN Inquiry requests.
  
  The core stack will have the following:
  Segmentation fault in naSAN_Fetch at 0x1002832ac ($t179562)
  0x1002832ac (naSAN_Fetch+0x44) e8ff000e         lwa
  r7,0xc(r31)
  (dbx) where
  naSAN_Fetch(??, ??, ??) at 0x1002832ac
  sqlBaseTable_Fetch@AF56_40(??, ??) at 0x1001698b4   <-- Does not
                                                   need to be seen
  
  Initial Impact: Medium
  Additional Keywords:  dump crash q san
  

Local fix

• If you are doing the same type of SQL queries, then limit them.
