Are you only seeing this on Python 3.11?

Hi @schweitzpgi
Yes, it's only been seen on Python 3.11, but more precisely, only on the Python 3.11 + arm64 + cuda12.6 + Fedora 42 configuration. Other Python 3.11 configurations (e.g. different architectures or OS) have not shown this failure.
The issue was initially seen in two separate CI runs on this specific configuration(refer: https://nvidia.slack.com/archives/C03KV6A81HT/p1770744080083629), which led to the test being disabled. However, I've since re-run the CI about 4 times on this configuration and have been unable to reproduce the failure. At this point, I suspect it's more likely a CI environment issue rather than a code bug.
