I have done it yesterday and up to now everything works as expected. I will 
report if the problem will occur again.

Thanks for the link, up to now condor was just working and thats it. But since 
this year we usally have about 10000 Jobs per  day (runningtime 2min up to 
2h) on 200 nodes. And therefore it seems I have to understand condor better.

I think on long term we also have to suspend long running jobs.

By the way, is it possible to just suspend a job with condor and continue 
without restarting and without checkpointing in vanilla universe under linux?

Or is it planned to implement checkpointing also for dynamic linked programs 
under linux?
