Description
This might or might not be related to MDEV-9674. We ran a lot of 5M record-transactions to duplicate the crash in that issue.
The server didn't crash, but during the day our server became very slow and quite unusable. A lot of trivial queries were waiting for a table level lock, when only using the primary key of the table involved. Queries stalling for 30 seconds and then timing out. Never seen that before. And, as far as I'm concerned, no reason why a table level lock should have to be involved.
A restart of the server fixed all this. I don't know exactly what to think of this.
Below the output of SHOW ENGINE INNODB STATUS. You can see that there are a lot of "Waiting for table level lock" entries, and I can't figure out why.
All those entries update some InnoDB table using the primary key.
my.cnf settings are in MDEV-9674
