Subject [jira] [Commented] (LUCENE-7108) Test2BPoints.test2D() failure
Date Tue, 15 Mar 2016 13:27:33 GMT


Steve Rowe commented on LUCENE-7108:

I didn't try to reproduce, in part because of how long it ran - the last hearbeat was:

   [junit4] HEARTBEAT J3 PID(29575@localhost): 2016-03-14T22:15:10, stalled for 77406s at:

I run Lucene-core monster tests via {{ant clean test -Dtests.jvms=4 -Dtests.nightly=true
-Dtests.heapsize=30g}} (via Jenkins's config).  This failing run took 21 hours to complete.
 I expect it will be faster next time - this is the first full run since the new monster tests'
timings have been recorded.

I had to switch away from my 400GB SSD to a 2TB spinning disk because the first time I ran
the monster tests after the 2B points and BKD monster tests were added, it ran out of disk
space.  I checked a couple times when the last two tests, {{Test2BPoints.test2D()}} and {{Test2BBKDPoints.test2D()}},
were running on separate JVMs, and the max disk usage I saw was 459GB:
