Hello, sorry for the latish response - we were on a weekend :-)...
Concurrency limits are indeed listed in negotiator log and in jobs.
As a test, I set my own concurrency to 1 and started initiating condor_run 'sleep 10000' jobs.
Slowly, bit by bit, there came more and more of them running. Not what I wants :(....
Ok... Maybe I do not understand the concurrency.
Assume I am the only user of the whole cluster. I want no more than 2 of my jobs running at any given time, no matter how many free slots there are. Should I set 'marcv_limit = 2' and set SCHED_ATTRS = Owner, etc, or should I do something more violent?
Many thanks in advance,

I did a condor_reconfig -full -all and am pretty sure limits are in the ads. Will check logs.
The annoying bit is that a test cluster works, the production one does not.
