Release Note Description

Additional information about the issue reported

There's no tail of /var/log and no additional information in artifacts, so it doesn't seem possible to further investigate this issue from my end. It seems possible it could be OOM, depending on how resource-constrained the machine running the tests is.

I wanted to restrict this to match LibraryImportGenerator SIGKILLs specifically, but it looks like ErrorPattern can't match multiple lines.
