We run AWX version 24.6.1 using the awx-operator in a k3s cluster.

Inside the awx-task pod the awx-ee container crashed with the following error message:

# kubectl -n awx logs awx-task-77b54f47c6-rbwbq -c awx-ee --previous

I've not been able to see any memory / cpu overload problems on the node running this pod.

receptor version:

$ receptor --version
1.4.8+d7fe592

Is this a bug in receptor? Let me know if you need more infos / logs.

Thx Joel

Causative seems to be the use of the return value of ParseTime() without checking for a nil value.
