2868544 - ASE shuts down under Business Objects (BI)

Symptom

  • ASE process just stops with no message in ASE log
  • There are no relevant messages in OS logs (for example /var/log/messages)

  • On BI side, once ASE has gone away, the BI console reports:

    Account information not recognized: The CMS system database is not available. The error cannot be rectified by the end user.
    Please report this error to your system or database administrator. (FWM 02088)

  • With OS tracing on the dataserver process or with ASE setting 'enable console logging' to ON, the only clue may be a message including 'Unknown Reason'
    • an strace on the dataserver pid would end with entries like:

12345 17:00:02 write(2, "Unknown reason\n", 15) = 15
12345 17:00:02 exit_group(-1) = ?
1256   17:00:02 +++ exited with 255 +++

  • The last message in ASE log before it terminates may be:

Job Scheduler Task jobs are Queued to tasks max = X.

  • The JSAgent log shows a disconnect message, which is an indication that ASE went down
    • This is likely to show up on the hour, for example at 11:00 or 16:00

-> JS: Task/Agent connection terminated.
Job Scheduler failed to receive communication buffer while reading message type.
Connection to Job Scheduler task terminated unexpectedly with error -4
Client message:
Message number: LAYER = (5) ORIGIN = (3) SEVERITY = (5) NUMBER = (6)
Message String: ct_results(): network packet layer: internal net library error: Net-Library operation terminated due to disconnect

Environment

  • SAP Adaptive Server Enterprise (ASE) 16.0 SP03 PL06 & PL07
  • Business Objects
    • At this time the issue is mainly observed with BI systems running on ASE
    • There is no indication that it should only happen with BI, so non-BI systems could be affected too
