The CLI command list-signed will result in an OOM if executed with only the --tag option specified.
list-signed
--tag
From a quick look, it appears this is because of an invocation of the hub API queryRPMSigs without any arguments.
queryRPMSigs
See: https://pagure.io/koji/blob/master/f/cli/koji_cli/commands.py#_2115
It seems like the logic there is somewhat backwards -- querying every signature in all of koji, and then subsequently filtering it to what's in a given tag. You'd probably be better using the tag option to discover a list of builds, and then querying for signed RPMs from those builds.
