Dear Lucene community,
This morning I found this exception in our logs. This was the first time
we indexed this data with lucene 9.10. Before we were still on the
lucene 8.x branch. between the last indexing with 8 and this one with
9.10 we have a bit more data so it could be something else that went
over an limit.
Unfortunately, from this log message I am at a loss for what is going
on. And what I could do to prevent this from happening. Does anyone have
any ideas?
Regards,
Jerven Bolleman
