I'd add the debugging information and send it to a log. Debugging info 
is good to have in any program, regardless. If you don't want all the 
debug all the time, add a command line --debug parameter or something 
to activate it.

If it sticks frequently I'd run it through the debugger:

perl -d myprog.pl
c    # "continue". Run the program until I stop you.
      # process runs for a while then hangs
^C   # break
      # now you can see what line number the program stopped on.
v    # print several lines of source w/ ==> pointing at the current line
.    # print the current line again

HTH,
