IT33408: CORE DUMP FILES ON DATA COLLECTOR CAUSE REMOTE LOG COLLECTION TO FAIL AND CORE DUMP

APAR status

• Closed as program error.

Error description

• Core dump files might be found on the data collector even
  though it continues to function without a problem. The core
  dumps are caused by remote log collection attempts by support
  when prior core dump files already existed. When this occurs,
  the remote log collection fails and no logs for the data
  collector are uploaded.
  
  Javacore, core, heapdump, and snap
  files can be found under the data collector log directory when
  they have occurred.
  
  When the core dumps occur because of the
  log collection attempt, you might also find remnants of the log
  collection attempt under the following
  directories.
  <data_collector_dir>/service
  - confdir.zip
  -
  devops.zip
  - logdir.zip
  - osversion.txt
  -
  version.txt
  
  <data_collector_dir>
  -
  CollectorLogFile.log.#
  
  Removing the core dump files from the
  data collector directory allows the remote log collection to
  work without core dumping again. Core dump files can be sent to
  support for analysis.

Local fix

• Remove the core dump files from the data collector directory.
