CML Environment Launch Failure – Torque Error

mehwish0093 — Mon, 06 Apr 2026 11:19:54 GMT

I am experiencing an issue while launching an environment in CML. After initiating the launch, the process runs for about 4 minutes and then fails with the following error:

"Torque was not able to complete launching your environment. For more details, contact your space admin."

Expected Behavior:
The environment should launch successfully and provide access to the workspace.

Actual Behavior:
The launch fails after ~4 minutes with the Torque error mentioned above.

Additional Details:

This issue occurs consistently on every attempt
I tested in incognito mode
I also tried using 4 different accounts, but the issue persists

Request:
Please investigate the issue with the Torque scheduler or environment provisioning and advise on a fix.

Thank you.

@mehwish0093 most of the times this happens for the heavy load of sessions for specific environment..

This is likely issue on their side (server); However, DevNet SandBox support stuff maybe out last week; We had Easter week! Hopefully, they are back today!

Try later today! Let us know.

Just a quick update on the Cisco Modeling Labs (CML) sandbox — it’s now back in the catalog and fully operational.

We recently completed a round of maintenance to improve stability and performance. Everything is now up and running smoothly, and you should be able to access the sandbox without issues.

Thanks for your patience during the maintenance window, and feel free to reach out if you run into any problems or have feedback to share!

There might be temporary glitch after maintenance. CML sandbox is fully functional for reservations
