As it turned out, the ZMQ errors are unimportant and the real culprit is cpu 
usage of ipcontroller. I have found out that it quickly hits 100% all time once 
the job queue reaches a few thousand (I'm a using 200 core cluster with each job 
taking ~90sec). Is this to be expected? Any suggestions how to mitigate the 
issue?
