Subject: ODB lock timeout, Difficulty running MIDAS on Rocky 9.4 
> try to replicate the issue ...

I see ODB lock timeout (and abort() of everything) in the dsvslice test station. We have 
about 15-20 MIDAS clients connected.

I am pretty sure we have not seen this problem until recently (and I have not seen it 
personally for a very long time). There were no changes to the MIDAS ODB locking code in a 
long time.

I suspect a recent change in the linux kernel. But I am likely to be wrong.

I have 1000 core dumps from this crash of dsvslice, and among them should be the 1 thread
that has ODB locked. Wish me luck finding it. Worst case is to discover that ODB is locked 
but nobody is holding a lock ("missing unlock bug"). This is hard to debug, I would have add 
tracking of "who was the last one to lock it, who forgot to unlock it".

K.O.
