"virtio-9p: unexpected EOF reading -- did the 9P server crash" error when running I/O intensive application on Docker for Mac Bets

nouvak · May 9, 2016, 12:58pm

Expected behavior

Docker should not crash for I/O intensive applications.

Actual behavior

If I start our application, it runs fine for about a minute. After that time, all the docker containers crash, “docker ps” command shows no containers running. This happens every single time for that use case.

I executed the “pinata diagnose -u” command and the first error I see is, as follows:

May 9 14:25:45 haris Docker[com.docker.driver.amd64-linux][85933] : virtio-9p: unexpected EOF reading – did the 9P server crash?

Steps to reproduce the behavior

The same behaviour occurs every time I execute our web application in Docker environment.
The testing environment consists of multiple Docker containers with Postgres, Redis and Django framework.

The use case that causes the crash of the containers involves the sending of multiple messages to the Celery distributed task queue.

Unfortunately, I cannot share the web application, however I would be able to include some diagnostics if you guys need some additional info.

If you need some additional info, please don’t hesitate to contact me.

I’ve got same error message while running official postgresql database with 5 databases, about 10 connections at the same time. It takes a couple of minutes to got this error, but it is reproducible.
Nothing special, only the port mapped to docker.local:5432 (rather than using dynamic mapping)

nouvak · May 9, 2016, 2:06pm

I can confirm that I have very similar environment as @sassrobi.
I am also running a couple of postgresql instances in docker containers, each of them having port exported to the host (port numbers 5432, 5433, 5434).

davetucker · May 9, 2016, 2:38pm

I’ve opened an issue for this on our bug tracker (#3035) and we’ll look in to it soon!
Thanks for the bug reports and for trying Docker for Mac!

nouvak · May 9, 2016, 2:49pm

Splendid!
If you need any additional info, I can re-run our application easily.
As mentioned, the crash of docker containers occurs in less than a minute in our case.

chrishiestand · May 10, 2016, 8:08pm

I’ve added a reproducible test case: https://github.com/chrishiestand/docker-mysql-import-bug

chrishiestand · May 24, 2016, 8:25pm

This no longer reproduces for me on 1.11.1-beta12 build 7528

sassrobi · May 24, 2016, 9:12pm

I can confirm that. It is stable for me since I upgraded to the mentioned version.

bryanl · June 5, 2016, 1:23pm

I’m still seeing this happen with Version 1.11.1-beta13.1 (build: 8193). I’m running a single postgres container, and the workload is not very high as it’s a very small database.

justincormack · June 5, 2016, 3:16pm

We are not using virtio-p9 any more, so I think it is a different issue - can you open a new issue with more details, in particular and messages in the log. Will do some testing with postgres.

bryanl · June 5, 2016, 3:20pm

Well now it get’s more interesting

This is the error message that led me to this thread. Do I possibly have a busted install?

As an aside, I’m running pg with a volume mount.

justincormack · June 5, 2016, 3:25pm

Ah we are still using virtio-9p for port forwards, it could well be related, but not quite the same… Will look into it.

justincormack · June 5, 2016, 3:27pm

Any way to replicate relatively easily would be appreciated, eg how are you running it, roughly how many connections, also state of netstat -a on the mac just after it crashes might help.

justincormack · June 5, 2016, 3:27pm

Internal issue #3660

johanneswuerbach · June 8, 2016, 10:33pm

Same here, when launching a “complicated” compose stack the VM reboots and I see “Fatal unexpected exception: Transfuse.Socket_closed” in OS X syslog before the VM is killed.

Sadly I can’t really share a test case, but could provide further logs as required.

justincormack · June 9, 2016, 9:53am

We think it may be fixed in the next beta (should be out later today), but we are not entirely sure, we cannot replicate with the test we have any more, but it may not be quite the same issue we are testing for. If you could re-test after the update that would be very helpful.

johanneswuerbach · June 11, 2016, 7:09am

Looks like the new beta solved my issue, thanks .

justincormack · June 11, 2016, 9:16am

Great! Glad it is solved!
