when running some google app engine tasks on dev server it completes with 200 status, but when deploying and running the same task on production the task don't get executed completely and get retrying until it use all retry count.
I think this may be something with task timeout, and increasing it may fix my problem but can't figure out how to do so!!!
BTW i used
print >>sys.stderr
to trace my code execution progress and every time the code stops at the same point
