Ishan Chattopadhyaya commented on SOLR-5944:
--------------------------------------------
Thanks for looking into the issue, Hoss.
bq. The comments says the changes were made to a github repo on a "solr_5944"
branch, but the linked repo doesn't have a branch with that name
https://github.com/chatman/lucene-solr/tree/solr_5944
Noble's last commit is: 4572983839e3943b7dea52a8a2d55aa2b3b5ca3a
bq. what is the issue that causes data loss
When it happens, my understanding is that some uncommitted in-place updates
don't reflect after a commit in a re-opened searcher.
bq. can you describe the "rarely" situation? is there a test that demonstrates
the problem?
TestStressInPlaceUpdates is the affected test. Used to happen once in around
2000 runs, on a 3Ghz 5960X CPU (I'm unable to reproduce, as I mentioned in my
previous comment, on dual 2.0Ghz Xeon E5 2658 V3).
bq. is this the same (non-reproducible) test failure that Ishan mentioned in in
his comment this morning (May16)

I think Noble is referring to the same. It could be due to some underlying
issue with either how Solr uses Lucene or how Lucene is flushing the dv updates
during a commit.
