A new 6.4-5 maintenance release is now available for the Qube 6.4 Core/Supervisor/Worker. This is a recommended release for all customers running Qube v6.4.
=======================================================
Highlighted changes
=======================================================
@FIX: timing issue where a subjob of an agenda-based job can be incorrectly left in the "blocked" or "pending" state even though there are no more agenda items to be processed.
@FIX: fixed unreliable "modify" behavior. Multiple modifies (for example, up then down) were behaving oddly.
@CHANGE: added code to automatically retire pending/blocked/running jobs when "modify" reduces the "cpus" ("instances") count.
@FIX: patched a timing issue where the requestWork() handler can sometimes put a running subjob back to "pending" (because it's marked to be passively preempted) even if there are no more agenda items left to process.
@FIX: fixed return data type of qb.submit() to be a list of qb.Job objects
@FIX: issue where modifying a job to reduce the number of instances can sometimes incorrectly retire ALL instances.
@FIX: random worker crash issue on Windows
