Lots of stuck queries after upgrade to 9.4
We upgraded to 9.4.4 from 8.4 We have tried 9.3.x in the past with success.
Unfortunately in 9.4 gets stuck 2-3 times a week.
Lots of queries seem stuck, that is they have waiting:false. Queries can be COMMIT or INSERT.
No blocking locks seem to exist.
strace reveals that all stuck processes they are in semop
semop(2064417, {{0, -1, 0}}, 1^C <unfinished ...>
ipcs reveals no shortage of semaphores..
Please any ideas very welcome, our service now in a very sad state..
