@tamalsaha is this planned to be part of an upcoming release?

[tamalsaha]

Yes. I looking to cut a release in a 1-2 weeks.

@tamalsaha when is this getting release? Thanks

[scottrigby]

Left feedback on #363, but can that be a follow-up to a new release that contains this fix?

[mbelang]

Is the memory problem fixed by this? If so would like to have a release of this please. Thx

[scottrigby]

@mbelang I haven't done this yet, but good feedback may be to build the app/image with this fix in place, deploy it and see if it fixes the issue?

[tamalsaha]

I have released v0.11.0 https://github.com/appscode/kubed/releases/tag/v0.11.0 . Please give it a shot.

[mbelang]

I'm testing it at the moment. I monitor for memory increase.

Out of curiosity, how much resources you recommend?
I currently set for limits and resources:

cpu:     150m
memory:  128Mi

[tamalsaha]

What you have set should be enough.

So far it restarted twice because of oom killed. So I suspect that the leak is still present. The only feature I use is the config map sync.

[tamalsaha]

Are you seeing any logs like https://github.com/appscode/kubed/issues/304#issuecomment-508024105 ?

[mbelang]

The only error log I see from kubed is:
Skipping failed API Groups: unable to retrieve the complete list of server APIs: kubed.appscode.com/v1alpha1: the server is currently unable to handle the request

It restarted 9 times since I updated it to 0.11 and the pattern is consistent. In the picture below, you will see where I updated to 0.11.

[tamalsaha]

Could you increase the memory to say 512MiB ? And then see if the pattern continues.

[mbelang]

Keeps increasing and reaching the limits. It's just takes longer as you can figure :)

[tamalsaha]

If it is possible, can you please email be the config file you are using? My email us tamal AT appscode.com .
