markForCollection may hang
There is a timing condition that can cause the markForCollection to hang,
as the commit record backlog approaches the StnSignalAbortCrBacklog limit.
This bug can be diagnosed in statmonitor data, by SessionStat03 flatlining
on 5 and ProgressCount freezing.
Workaround
The chances of hitting this bug are timing-dependent as well as depending
on a commit record backlog. Increasing the STN_SIGNAL_ABORT_CR_BACKLOG
(#StnSignalAbortCrBacklog) before starting the markFocCollection will reduce
the likehood of hitting this bug.
