My containers runs resilio sync (similar to Bittorrent) with many share folders. I have several similar containers. After upgrading to beta39, Docker vm keeps restarting after running for a short time.

Something I found in the log:

BTW I switched back to stable and it works normally.

Thanks for your report. The assertion is here which looks like it's caused by the incoming ethernet frame being too big for the buffer. I suspect this is because of a miscommunication about the MTU on the link. I've escalated this to our networking team.

Exact problem here, this version is useless for anything network intensive. Could you please provide links to previous installers? #1120 [Update: I found a 1.12.x installer from a while back and it works ok for now. Thanks!]

[bgrieder]

@sra The proposed workaround in #1378 (comment) may or may not work for you.....

[Palid]

While this isn't fixed I advise using this version: https://download.docker.com/mac/stable/1.12.6.14937/Docker.dmg

It's older one, but at least it doesn't randomly crash.

This has now shipped in the beta channel, so any version since 17.03.0-ce-mac2 should have the fix in. If you do see this again in an newer version, we'd appreciate a fresh issue with diagnostic logs so we can continue to track it down. Our fix sets the MTU to a firm 1500 rather than autonegotiating it, so we are fairly confident it should not re-occur. Thanks for the help with tracking it down!

This looks like its happening again on:

Version 17.06.0-ce-mac18 (18433)
Channel: stable
d9b66511e0

[djs55]

Without diagnostic logs I can't tell for sure but this could be another instance of #1789. Try setting: Whale menu -> Preferences... -> Proxies -> No proxy and see if it fixes it. If so the fix will be in the upcoming 17.06.1 release, due this week.

Happening for me with Docker Desktop 2.1.0.1 (stable)
