Hoss Man created SOLR-5794:
------------------------------
Summary: DistribCursorPagingTest chewing up too much ram in
nightly mode? (OutOfMemoryError: GC overhead limit exceeded)
Key: SOLR-5794
URL: https://issues.apache.org/jira/browse/SOLR-5794
Project: Solr
Issue Type: Test
Reporter: Hoss Man
Assignee: Hoss Man
https://builds.apache.org/job/Lucene-Solr-NightlyTests-4.x/524/consoleText
Looks like nightly + some unlucky seeds are causing some of the constants used
in picking how many random docs to include in the index, and how many random
sort criteria to use to get a bit extreme...

...i'm probably using "atLeast()" in a few too many places ... i'll dial this
back
(FWIW: I can't reproduce the OOM on my machine, but with just that seed, the
test takes ~2min; that seed + -Dnightly=true is 5min+)
