APAR status

• Closed as program error.

Error description

• It is possible for the server to crash when monitoring is
  enabled. The server checks to see if there is backup data for
  VMs. If that fails, it will try to output a message to the FFDC
  log file. This causes the server to crash since there is a
  mismatch of data types being used.
  
  Spectrum Protect Versions Affected: 7.1.x and 8.1.x on all
  supported platforms
  
  Customer/L2 Diagnostics: The callstack for this crash will looks
  similar to this:
  
  sprintf()+7B, Unavailable
  PrepDispArgs()+7AD, outvarg.c(911)
  outFFDCLog()+1E2, outvarg.c(373)
  CheckVirtualM()+100A, admnode.c(31631)

  beginthreadex()+107, Unavailable
  endthreadex()+192, Unavailable
  BaseThreadInitThunk()+22, Unavailable
  RtlUserThreadStart()+34, Unavailable
  
  The key piece here is the outFFDCLog entry. That is also found
  in the dsmserv.err or dsmsvc.err log
