Kubernetes Spamming Dmesg With "No Destinations Available"

[brando56894]

I have Nextcloud and Plex setup using the official apps, and they work/I can access them with no issues, but in dmesg there are tons of messages stating the following

Code:

[36770.301553] IPVS: rr: TCP 172.17.204.52:5432 - no destination available
[36772.351575] IPVS: rr: TCP 172.17.204.52:5432 - no destination available
[36773.024678] IPVS: rr: UDP 172.17.204.31:32412 - no destination available
[36773.049810] IPVS: rr: UDP 172.17.204.31:32414 - no destination available

In the ENV vars of one of the Plex containers I see this

PLEX_UDP_PORT_32414_UDP

udp://172.17.204.31:32414

The line is apparently for Nextcloud's postgres DB.

NEXTCLOUD_POSTGRES_PORT_5432_TCP

tcp://172.17.204.52:5432

I'm pretty familiar with Docker and have about 12 containers running, but have never really messed around with k8s that much, so I have no idea how to fix this/get it to shut up.

Edit: there are also other errors about pods/containers not running and other things, but like Plex aand NextCloud seem to work without issue.

Edit 2: There are 8 containers for plex and nextcloud that are shown as down (I'm using portainer to manage my docker containers) so I removed them, applied an update, and they're back in portainer, but are still down, and Plex and NextCloud are still happy.

@brando56894 this is an upstream kube-router issue and should be resolved in latest nightlies and the fix will be available in 21.08 release as well ( which is due soon ). Can you please confirm if you are seeing this on latest nightlies or if you are not willing to make the switch to nightlies, can you please let us know if this persists in 21.08 release ? Thank you :)

oh ok, I just updated to TrueNAS-SCALE-21.08-MASTER-20210823-132921 and so far there is only two mentions of the above but only from Plex

Code:

 
Aug 23 16:03:26 truenas.brandongolway.us kernel: IPVS: rr: UDP 172.17.204.31:32412 - no destination available
Aug 23 16:03:26 truenas.brandongolway.us kernel: IPVS: rr: UDP 172.17.204.31:32414 - no destination available

I'll keep an eye out for more.
