After applying the patch documented in knowledge doc KB000007519 - "Trap Exploder 1.6.PL2/PL3 crashing on Linux", located at https://comm.support.ca.com/kb/trap-exploder-16-pl2pl3-crashing-on-linux/KB000007519 the trapexploder file is no longer created in the $TRAPXROOT/log directory.
This is functioning as designed. Information is still written to the $TRAPXROOT/log/trapexploder.log file.
