Local fix
Problem summary
On HP-UX, when the configuration option NumEventsToCatchUp is set to a value other than zero, the agent might core. The agent continued processing, even though the parsing of the restart file line was treated as a failure and the required field values were missing (NULL). The problem occurs on Log File Agent v6.3 and v6.2.3.2.
Problem conclusion
Handle the return value properly from parse function, so the parsing of the restart file row continues. The fix for this APAR is included in the following maintenance vehicle: | interim fix | 6.3.0-TIV-ITM_LFA-IF0002 available at http://www.ibm.com/support/docview.wss?uid=swg24037287.
