This page is a very useful page, never seen it before.
If I envounter the problem again I'll try to use fulldebug mode for the startd to
find out more about this.

Sorry but in the meantime Condor 6.7.8 had been replaced with 6.8.10 and all log files were
removed to start from scratch.
Sadly I found that the problem was not related to the development version
but to the fact that I forced condor to drop claims to give similar chances to new users (to be able
to claim a machine). When more than 1000 jobs were queued somehow the claim process died
and I constantly received "DEACTIVATE_CLAIM_FORCIBLY" commands that shut down my
already running processes.

The computation time varies between 1 and 100 minutes for a single job. Probably
the jobs you saw in the log file were doing similar computations and started at roughly
the same time. (I guess DAGMan submitted the jobs and at the first negotiation cycle
a few computers were matched.)
