_Never_ use *Eligible in production code. It is so dangerous that IBM have even "hidden" it as an option on the command. Prompt for RCLACTGRP and try and even find *ELIGIBLE as an option! I think the only place it is mentioned is in the help text. Not only will it cause the kind of problem that you have experienced, but it may cause other system functions to fail. It is OK to use it as a convenience when testing, but never safe to do so in production code.
It is also not a good idea to run real ILE programs/service programs in the DAG, although many people get away with it. AT least until they satrt usning files in service programs and .......
See our article "The seven deadly sins of ILE" if you want to know more. Go to www.eservercomputing/iseries and search for seven deadly sins. I would give you the URL but they are a bit screwed up at the moment.
Couple of points:
1. Service programs (i.e. *SRVPGM) should generally be compiled with the activation group set to *CALLER. That should solve your problem.
2. RCLACTGRP *ELIGIBLE within programs is usually not a good idea (in my experience). Consider reclaiming activation groups by name.
One more point:
If your calling program is an ILE program, consider specifying a named activation group rather than the default. Even QILE would be better. Reclaim the activation group when you know it will no longer be needed.
Hope this helps.
