Mark Miller commented on SOLR-4205:
-----------------------------------
That's weird - I don't think there is anything in the test that looks at the
multiplier...so not sure how that would still matter.
bq. we should maybe run the test suite locally with -Dtests.nightly and
-Dtests.multiplicator=3 first
That actually passed for me a few days ago on my dev machine when I tried, so I
don't think I can learn much on my machine.

> I had to kill ASF Jenkins Clover builds two times after several 10 hours of

> To me it looks like there is something wrong with the test runner. In other
> cases this totally-hanging threads were caused by permgen-errors, but nothing
> like this in the logs. It looks like the slave is waiting forever to get some
> messages from the master or vice versa.
> You can imitate clover tests on ASF Jenkins by running:
> {noformat}
> ANT_OPTS="-Xmx1536M" ant -Dtests.jettyConnector=Socket jenkins-clover
> {noformat}
> (the ANT_OPTS are just for the generate-clover-task using lots of memory -
> totally unrelated. This is just needed after the tests ran successfully).
> jenkins-clover calls run-clover task which automatically gives more memory to
> the child JVMs, so maybe this is related and needs more memory. You can find
> that in the main common-build.xml file, where you will find a property
> definition if="run.clover" giving more heap and code cache to childs:
> {code:xml}
> <condition property="tests.heapsize" value="768M">
> <isset property="run.clover"/>
> </condition>
> <property name="tests.heapsize" value="512M"/>
>
> <condition property="tests.clover.args"
> value="-XX:ReservedCodeCacheSize=128m">
> <isset property="run.clover"/>
> </condition>
> <property name="tests.clover.args" value=""/>
> {code}
> (maybe tweak that if Solr needs more memory - Lucene clover passes fine).
> I disabled clover tests for now.
