[Condor-users] Recursive DAGman

[Ian Cottam <Ian.Cottam@xxxxxxxxxxxxxxxx>]

Without going in to too much detail at this stage, we have a user who is
trying to get a recursive DAGman to work.
Can anyone point me at examples or advice on this?

At the end of the DAG script he does a convergence test and if necessary
re-submits the DAG with updated files.
At first this was failing because DAGman thought it was the same job and
the lock file stopped it running.
He 'fixed' this by renaming the recursive DAGman script.

This is the comment I got from him
"So we can see, it has some issue that the parent process (I'm not
actually sure whether this is the parent dagman process or the parent
script) exits, causing the newly launched dagman process to get signal 3
and thus enter recovery mode. It does this infinitely, never escaping from
this loop until I removed the dagman process from the queue using
condor_rm."

I can supply more details if anyone can help; I've also asked him to
create a bare bones example of the problem
(the real one is quite hairy/messy).

Thanks all
-Ian
