# genenetwork2 CD sometimes fails to restart

* assigned: arun, fred

When the genenetwork2 CI job passes, the genenetwork2 CD is restarted. Sometimes, this restart fails even though the CI job ran successfully. This manifests as a https://cd.genenetwork.org page with all green badges, but with a message that says "GeneNetwork CD is down!". Restarting the entire CI/CD container or rerunning the genenetwork2 CI job and thus restarting the genenetwork2 shepherd service fixes this issue.

This problem is specific to the genenetwork2 CD and not the genenetwork3 CD. I suspect this is not a problem with the CI/CD Guix configuration, but rather with genenetwork2 itself. More debugging is necessary.

A reminder that CD logs are publicly accessible on tux02.

## Resolution

I am closing this issue since I believe these restart failures are due to occasional breakage in genenetwork code, and are not a problem with the CI/CD system itself. Please reopen if there is reason to think otherwise.
