As you can see the system starts utilizing swap at some point, with so many processes. Some time ago we had decided to keep the connections from the pool open for longer

You've shown the system has used swap but not that it is swapping. Having swap in use is fine - there is likely plenty of code and whatnot that is not being used so it dumped it out to swap. However if you are actively moving data to/from swap that is bad. Very bad. Especially on linux.


To tell if you are swapping you need to watch the output of say, vmstat 1 and look at the si and so columns.

Linux is very swap happy and likes to swap things for fun and profit.
