Comment (by jitter):

 An exception that is also triggered sometimes (especially in cases where
 the load on the cluster nodes is high and starting Matlab takes some
 time):

 The log files look normal, though.

 P.S. I know that this is a very specific setup and it might be hard for
 you to reproduce the bug. The only thing I can offer is that I'll run
 tests whenever you post a script here.
