Error description
IBM Tivoli Storage Manager server can crash when the diagnostic command SHOW THREADS command is issued. No related entries will be seen in the dsmserv.err file. The traceback shows the following: Segmentation fault in FindTraceBackTable at 0x10022260c ($t834) 0x10022260c (FindTraceBackTable+0xc) 84040004 lwzu r0,0x4(r4) (dbx) where FindTraceBackTable(??) at 0x10022260c PkFindProcName(??, ??, ??) at 0x1002226c0 pkShowCallChain(??, ??, ??, ??) at 0x100222ac0 PsShowThreads(??, ??) at 0x1009141a4 PkShowThreads(??) at 0x1000165e8 ShowCommand@AF12_4(??, ??, ??) at 0x100913cbc psCommand(??, ??, ??) at 0x1009133a8 AdmShow(??) at 0x10091d4b8 AdmCommandLocal(??, ??, ??, ??, ??) at 0x10014fb18 admCommand(??, ??, ??, ??, ??) at 0x100150cfc SmAdminCommandThread(??) at 0x100713c44 StartThread(??) at 0x1000151ac A similar crash was described as APAR IC71010 but here the crash occurs in FindTraceBackTable whereas IC71010 crashed in PkFindProcName. The only other circumvention at this time is to not use the SHOW THREADS command. Platforms and versions affected: All supported versions of Tivoli Storage Manager server on AIX Initial Impact: Low Additional Keywords: tsm server crash dbx abend 65102 IC71010 serverperf.pl serverperf debugging
Local fix
None. The command which caused this is the undocumented command "show threads". This command should only be used at the direction of Tivoli Storage Manager support. If more than one crash occurs which matches this symptom, stop using this command. If you need to find out details on threads you could also use Operating System utilities like pstack, gstack, procstack or similar.
