Abstract

OSP-DB-OTHER-WAIT FILE DESTROYED WHILE THERE IS STILL SOME
OUTSTANDING WORK BEING DONE ON IT'S BEHALF CAUSES JOB TO HUNG

Error Description

Background tasks within the operating system to control the    
order in which certain metadata kept for objects at the OS      
level are written to disk. We do this for object recovery      
purposes in the event there is some kind of system              
interruption or outage from which objects need to be            
In this case, it looks like a file was destroyed                
while there was still some outstanding work being done          
on its behalf in one of these background tasks and              
the timing of everything caused the background task to be stuck
in a state where he will never be woken up so that he can send  
a response to other jobs that he has completed his work.        
Those other jobs sit and wait for a confirmation that never    
comes.                                                          
                                                               
We'll introduce some code changes that may reduce the          
likelihood of the occurrence of this problem, and leave some    
additional diagnostics for us to look at when it does occur.
