We are experiencing issues with High CPU usage on dockerd whenever we enable the logspout-logstash container.

Is this a problem with logspout or this plugin?

I'm experiencing the exact same problem with a host running 57 containers.

Docker version 1.12.4, build 1564f02

we have the same problem on docker 17.06 and logspout 3.2.2
it is not an issue with logspout, as we do not have the problem with other log adapters using logspout (and the same docker version)

It would be great if someone could do some profiling to locate possible issues. I don't use this project myself at the moment and would be very grateful if anyone who does could help out. Thanks.

i just downgraded docker to 17.03, which fixes the issue

[maxekman]

Is this still an issue?

[nikosch86]

i can not reproduce it with docker 17.05 and logspout v3.2.3 on our staging setup
next week i will try on our production which has a much higher volume of logs
