Hi @stinger we think this looks like it could be a bug.
Would you be OK to report this to JIRA so that our bug research team can look at it, please? The URL is jira.percona.com and the forms there will lead you through the information that’s needed, and you’ll be kept informed on progress. You can also check if it’s been spotted before.
The open source forums are more “information” than “bug” though you will get the forum bug badge if you come back and paste the JIRA report link here
