Hi Mike,
I am attaching the dump that I created by putting
-XX:+PrintClassHistogram in catalina options and by issuing a kill -3
command. The machine was not in a bad state (i.e. it was not doing
frequent Full GC cycles yet) but the kill -3 forced it to do a Full GC.
If you want I will wait
Are you using IndexReader.reopen to open those new searchers?
Can you capture a memory dump when GC kicks in? I'd be curious to see
where all the "new" garbage is coming from... I don't think 2.3.2 ->
2.9.2 should be generating more garbage.

Indexing happens in a different thread on intervals. I open a new
IndexWriter for each indexing session. After indexing session if there
is a modification in the index I close the searcher and open a new one.
I have two searchers that I flip flop when opening an index.

How do you reopen your searchers after indexing?
Do you keep a single IW open for all time?

Indexing happen with frequent intervals on our indexes, but I think
searching is the cause of the issue, because as soon as the indexes are
hit with a lot of searches, the gc cycles become more frequent.

Is this during indexing or searching?

Yes, quite
