[TEC] task in rule fails due to strange return from wsnmptrap

We are trying to forward some TEC events to HPOV via a script using the 
'wsnmptrap' command.  If I run wsnmptrap from the command line, I get this odd 
message:  "wsnmptrap: No such service defined, using default snmp-trap port".   
I don't understand what that means, nothing in the DM manuals is helpful.  My 
HPOV guys here just say "ignore it, it's meaningless".  Even though I get that 
error(?) message,  the trap still succeeds and shows up in OpenView.

The TEC rule which calls the script runs successfully ... the action 
successfully executes the exec_program template which runs the perl script. But 
when I check task results in the TEC console (click on the blue whirligig in 
the far left column) it shows 'task status' is 'FAILURE' with 'exit status' of 
'255'.  The message that is supposed to be sent from TEC never makes it to OV.

This same script runs from the command line without any hint of trouble .... 
same script .... from command line, succeeds; from TEC, fails.  I added some 
'debugging' statements ... print env to log, etc. etc. ... when TEC runs it, 
nothing.  When I run it command line, works exactly as expected.

exit 0;



=================================

... even though I'm forcing an "exit 0" at the end, TEC seems to think this 
script is returning 255 ... the script is chmod 775, and the logfile is a=rw, 
so there's no chance of any permissions problems.  Originally the call to 
wsnmptrap was a system() call, but I changed it to $rc=`` in order to trap any 
possible return.  No help, no difference in behavior except that at the command 
line I don't see the message about 'no such service' because of course it has 
been trapped in the var $rc and I'm not printing that.  Anybody have any ideas 
on how to further troubleshoot or fix this?
