Yes, I think I remember talking about this during one of the phone calls.

I hunted through the queues, and I didn't find such a ticket, either.

I've created a PR for it: 890 (condor_hold shouldn't kill DAGMan).

You can create a condor-admin ticket for this if you want to.

Stuart,

Okay, I have this ticket.

As I mentioned, Gnats PR 890 also relates to this.
