Containers Frequently Disappearing - osxfs problem?


(Bryce) #1

Expected behavior

Containers to persist on the system for more than 5 minutes.

Actual behavior

Containers are running, then in an instant are gone and not visible even with docker ps -a

Steps to reproduce the behavior

  1. My best guess is that it is a throughput issue that is breaking the mount. The last 2 times it crashed it was while I was doing a large import into a container based MySQL instance (500MB mysql import). I was using docker stats to monitor the load, and half way through all the containers disappeared and were not listed in history (docker ps -a)

Hi Bryce,

We are investigating a load-related VSOCK crash that you may have run across. I don’t think a fix will make it into Beta 9 but we are hopeful that it can be resolved for Beta 10.

Thanks for your report and please accept my apologies for this frustrating defect.

Best regards,

David Sheets
