The appservice plan type is P1v2.
It runs in the Western European region.
App services are nodejs services that run in containers.
There is nothing suspicious in the metrics and log files.
It does not use half of the computing resources, but the memory usage is low.
The cpu usage jumps when the app service plan is restarted, so all app services. But this is obvious.
I've been running this service for a long time, but these problems have only just appeared. It hasn't been a release for a long time either, so it can't be that a new feature is causing the error, and the logs are fine.
Anyone have any ideas?
