I don't know what reuti suggested so I might be repeating...
How I debug the tight integration tasks: submit a job, set the 
environment variable JOB_ID to the job's number, SGE_TASK_ID to 
undefined, or to the required task nubmer ..
You can also try to debug with "dl 1" (source $SGE_ROOT/util/dl.sh or 
dl.csh depending on your shell) and start qrsh in this mode.

hope this helps,
