It looks like that is problem we are having. We are on 0.92 so we don't get the patch. But one
solution seems to be increasing the privileged handlers. How do we increase the number of privilege
handlers?

What JVM (I don't know what (20.10-b01 mixed mode) is).
I see a bunch of this:
"PRI IPC Server handler 5 on 60020" daemon prio=10
tid=0x00002aaac10a1800 nid=0x92f waiting for monitor entry
[0x000000004ab0f000]
java.lang.Thread.State: BLOCKED (on object monitor)
at .....
But when I go to look for other instances of the object monitor, I
don't find any. I see this for each instance of BLOCKED (Or at least,
the two or three I checked).
Whats your OS?
