Subject [jira] Updated: (DERBY-4037) On Z/OS storetests/st_reclaim_longcol.java fails with a large number of pages

Mike Matrigali updated DERBY-4037:
----------------------------------


thanks for the new report.  It looks like the test needs some more tweaking.  The new output
shows that the wait at end did allow for the system to free up a bunch of pages, vs. the previous

report so I don't think there is a real problem here.  But the test really wants the free'ing
to come
in the loop so that the subsequent insert can use the free'd pages of the previously committed

deleted.  For some reason this machine must not allow as concurrent background thread work
as other platforms.  I'll think about how best to change the test.
