Looks like it tried to archive a log file that was still open.

Sue LoVerso added a comment - Jun 23 2015 04:49:25 PM +00:00 It is unfortunate sanitizer does not generate core files. I've run 1000 iterations of this config successfully. I'll bump it up to 10k and study the code.

Sue LoVerso added a comment - Jun 24 2015 04:01:33 PM +00:00 Although never able to repro this assertion, I found a code path with a window that could incorrectly move sync_lsn forward during a checkpoint and allow an in-use file to be considered available for archiving. Testing fix now.
