Subject Re: Cleanup blocking snapshots - Options?
Date Mon, 15 Jan 2018 05:17:58 GMT
Disabling the snapshots is the best and only real option other than
upgrading at the moment. Although apparently it was thought that there was
only a small race condition in 2.1 that triggered this and it wasn't worth
fixing. If you are triggering it easily maybe it is worth fixing in 2.1 as
well. Does this happen consistently? Can you provide some more logs on the
JIRA or better yet a way to reproduce?
