Are you using the "$SERVICEGROUPMEMBERS$" macro in your commands?
If so, it's quite likely you're running into the environment limit
so the command fails completely. If you're also using embedded perl,
that would explain why you don't see the error when using perl plugins.

I fail to see how that macro can be relevant for checks though, but
that's the only thing I can think of.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
