All of @Damans227 comments are valid. Most important is takeBackup using up all of the 5 worker threads present on each kvm host. Operations like Start/Stop/Reboot/Migrate didn't use to wait for in-sequence commands like TakeBackup. But now someone can start 5 long running TakeBackup commands on a host. Until they finish Start/Stop/Reboot/Migrate operations will be stuck. We need a concurrency cap for TakeBackup commands per kvm host. Maybe TakeBackup can take 2 or 3 slots per host, but using all 5 slots at a time is not a good idea. -- This is an automated message from the Apache Git Service.
