Will Johnson commented on SOLR-240:
-----------------------------------
i get the stacktrace below with the latest from head with useNativeLocks turned
off (from my patch). this took about 2 minutes to reproduce on my windows
laptop.
one thing i thought of is that local antivirus scanning / backup software which
we run here may be getting in the way. i know many other search engines / high
performance databases out there have issues with antivirus software because it
causes similar locking issues. i'm disabling as much of the IT 'malware' as
possible and seeing better results even with default locking however i had
everything running when i had good results with the native locking enabled so
it still seems to be a good idea to use the patch (or something similar).
