Thanks for the detail. It appears that you're not accumulating
documents in memory, which is the problem I assumed you had, but
rather instances of a ThreadLocal cache. That's a new problem I
haven't seen before.
I'm going to change the ThreadLocal Converter cache to use an
LRUCache so it never grows beyond a certain size.
I'm not sure this will prevent the Tomcat messages, which appear to
be complaining about the existence of the ThreadLocal rather than
about the fact that it's growing. But it should prevent the memory
"leak" (which I would have expected to be a very slow one anyway.)
As to numbers, there are two of these caches in a ConversionRules
object, and there will probably in most cases be one ConversionRules
object per Configuration, which equates to a s9api Processor. So
this explains why the messages come in pairs.
