It's been about 48 hours and haven't seen the issue since doing this.
Great, thanks for verifying. From your report 5.16-rc2 has the issue, is 5.15 fine?
I can check that out sometime in the next few days, but IIRC I pretty sure the issue hadn't surfaced before the 3rd or 4th of November. I pull from master at least every 2-3 days, so there's at least a timeframe. -Kenny -- Kenneth R. Crudup / Sr. SW Engineer, Scott County Consulting, Orange County CA
