Timeout: PBJ session not going idle

cirrus — Tue, 21 Apr 2026 06:50:12 GMT

Hi,

We newly upgraded to CML (previously CDSW). The jupyterlab-runtime sessions go into a timeout according to the value set in the configuration - but the PBJ-runtime sessions not. Right now we assume that the PBJ sessions just don't go into some sort of idle state. Could that be? What could prevent it from going idle? How can we make that the user sessions are timeouted after the time set in the config?

Thank you in advance.

Correction: it is not just PBJ. Also for rstudio sessions. So the congif setting was not taken. What could we do?

In other words: Why does this option not work:

Hello @cirrus

Greetings from Cloudera Community. This is an Old Post, yet I am posting a response for Wider audiences. CML had a Bug causing PBJ Runtimes not respecting Timeout [1] & the Bug has no Workaround. This Bug is fixed in CML v2.0.47 [2].
