I have a ticket open on CHR rebooting if another CHR with several ties to it is running too, and the response said it was related to L2TP; recently I’ve got a notification that a fix has been done and should make it to the next release. Hopefully it is the same issue.
7.3, and the issue has appeared after upgrade to that version. Before, I was running 7.2.? and no reboots. 7.3.1 has been released before I’ve got the feedback on the ticket hence I don’t expect it to be fixed there.
