Yeah. That's a reasonably normal amount of timing.
What happens is that the script detects a lot of btlaunchmany that are
suddenly gone. Either they are still there, and not showing up, or they
are dead. It could well be that they've crashed.
BTW, I've disabled the cronjob now since it sends an email to the slaves
list every 10 minutes :-) So right now, nothing happens.

Nope, that would be really weird. But it could well be a bug in the perl
library Proc::ProcessTable as well.

I did that. But it's a bit hard to catch it at the right moment. I
*think* I've seen both.

Ok. good.

Afternoon your time or mine ;-)
I'll be online most of the day CET (~GMT), and I can also be online in
the evening if you need it.

Oh. Could *that* be where the problem comes from? Ithought the ()

Oh :-) Didn't even know it was there.
