Hey @rotaugenlaubfrosch!

The reason that the session may be stuck in a pending state could be that your login nodes aren’t able to see connection.yml generated on the compute nodes when starting a session.

Start with checking if your file system writes from your compute nodes are syncing quick enough to your login nodes.

Someone had a similar problem not too long ago:

Interactive sessions stuck at starting stage

Make sure that compute nodes are syncing their writes properly. connection.yml is generated on the compute node directly. If writes from compute nodes aren’t being synced quickly enough to your file system, then that would explain why the login node is stalled because its waiting for connection.yml to exist. The home directory is similar to IPC, for example the login node is looking for /jupyter_test/output/694741ad-a664-4eee-924a-c0db3dd9961b/connection.yml
