Thank you very much. I didn't anticipate such a difficult complicated
cause. The user agreed to try the patch tonight. I'll report back the
result as soon as I got it from him.
The test ran successfully without hang for 24 hours. It was run with your
patch + the following:
BTW, in LWLockWaitForVar(), the first line of the following code fragment
is not necessary, because lwWaitLink is set to head immediately. I think
it would be good to eliminate as much unnecessary code as possible from
the spinlock section.
proc->lwWaitLink = NULL;
/* waiters are added to the front of the queue */
proc->lwWaitLink = lock->head;
Regards
MauMau
