That said, we are observing ST replication errors. Seems to go in
bursts. Haven't checked carefully, but seems to correlate with ST
validation failures (SERVICE_TICKET_VALIDATE_FAILED).
So it appears we might be busting our ST cache. It's currently
configured for 10k entries (prior load analysis showed as sufficient),
with no overflow to disk, and LRU eviction.
Given the ST looping, it seems feasible cache "flooding" could be behind
our problems.
Plan to turn on overflow-to-disk for the ST cache to see if it solves
the issue.
Are you able to possibly replicate it in a test environment? jvisualvm
is nice for looking into what's using memory.
