Bug in Mailman Problem

We are seeing a "Bug in Mailman" now appearing in many of our mailman lists across multiple servers. It is only triggered when you go to view "Tend to Pending Moderator Request" page. It has something to do with the request.pck file. Removing the file fixes it. However the list no longer sees any pending moderator requests if there were any. We see this on lists with no pending requests and we see it on lists with pending requests. I strongly believe this is a cPanel issue as it is impacting multiple lists on multiple servers and it seemed to pop up in the last 48 hours.

  Hello Jim, In ticket 9323441, the solution was to remove the corrupted pending.pck file from the /usr/local/cpanel/3rdparty/mailman/lists/$list-name/ directory. Note this removes the pending requests for the mailing list. Additionally, internal case CPANEL-23687 was published in cPanel & WHM version 76 to help prevent this from happening in the future: Fixed case CPANEL-23687: Ensure python pickle sanitization preserves integer keys. Thank you.
