APAR Error Description / Circumvention
-----------------------------------------------
We have background tasks that we use within the operating system
to make sure we control the order in which certain metadata we
keep 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/outage from which objects need to be
recovered. In this case, it looks like a file was destroyed
while there was still some outstanding work being done on it's
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. So, those other
jobs sit and wait for a confirmation that never comes.
we'll introduce some code changes that 1) may reduce the
likelihood of the occurrence of this problem, and 2) leave some
additional diagnostics for us to look at when it does occur.
CORRECTION FOR APAR MA48009 :
