Hi all, again;

I've enabled the core dumps and let it go for some day waiting for the issue to reoccur.

Meantime I've also upgraded the poolmon script, as Sami suggested.

It seems that the upgrade has scared the issue away, because it no longer occurred.

Maybe the problem is related to the way the old poolmon talked to the director daemon? I'm not very inclined to downgrade poolmon to catch a traceback, but can do if neccessary.
