Erick Erickson updated SOLR-7836:
---------------------------------
Attachment: deadlock_5_pass_iw.res.zip
Here's a fail with passing the index writer from addDoc0() to addAndDelete, my
first attempt at a "fix".
I commented out the necessary lines rather than add or delete them, so the line
numbers should correspond to the checkout I mentioned above.
> Possible deadlock when closing refcounted index writers.
