I'm managing two database servers, one 3.23.52 and one 3.23.52-Max
(using innodb tables on that one).

They are both running along fine until they suddently start to
accumulate a lot of treads (a lot ~= 200-300), the state of these
threads is mostly "closing" and "opening" tables. This drives up the
load to amazing numbers and I'm forced to shut the mysql-server down.

Since I'm running these servers in a shared environment I got a lot of
users using these servers, and so far I haven't got any grip on whats
causing these problems. I got these problems on both servers (one with
max and one without), both servers got diffrent users.

I've ruled out hardware problems since I get exactly the same behaviour
on two independent servers.

It would be great if sombody knows the answer to my questions bellow:
- is there any know problems with mysql on linux? or with 3.23.52 that
  should cause this behaviour

- what should I do to find the error, my logs shows nothing pecuilar.
  I'm currently dumping a processlist each five seconds to a file.


regards
/Lars
