   Is it possible that you do check which tasks are in "running" state for some 
time when it happens and maybe try to find some correlated logs from scheduler 
and task executtion - and ideally also find the logs from another task instance 
of the same task that was not found in "running" so that we could compare them 
and see the difference? 
   
   I preseume that there is some kind of race happenin that will somehow skip 
removal of the task even if it has been completed. - but seeing the logs and 
comparing them could narrow down the searrch an might allow us to come up with 
a plausible hypothesis.
   
   Question - do you run deferrable tasks / triggerer ?  Maybe somehow there is 
a problem with deferrable code ? (wild guessing now after looking into some 
possible paths).
