Hoss,
After investigating more, here is the tomcat log herebelow. It is indeed
the same problem: "exceeded limit of maxWarmingSearchers=2,".
It is an indexing box and the comment says that we could rise this number
to 4 or something. I can do that but I have four questions though:
- is it something that can happen anyway ?
- what are the actions in case it does (since re-committing the same docs
with a try-again mechanism is not re-committing) ?
- I was in the impression that no new searchers are created if I don't do
search. And I was not searching at that time. Where is this searcher coming
from ?
- is there a way to disable searchers during indexing since I precisely
don't want warming during indexing ?
Thanks a lot.
