             Summary: OpenCloseCoreStressTest opens too many files (causing it to fail often)
                 Key: SOLR-5345
                 URL: https://issues.apache.org/jira/browse/SOLR-5345
             Project: Solr
          Issue Type: Bug
            Reporter: Robert Muir
             Fix For: 4.5.1


Typically the symptom with jenkins is strange socket failures (because sockets are files too).

On my machine though i got the nice too many open files from lucene because it just happened to fail that way.

In addition to holding thousands of open files, this test creates 90 *megabytes* of logging output!

Can we tone down the test? I havent looked at all: but it doesn't seem necessary to have huge numbers of cores/indexes to test the functionality, we should be able to do this with relatively small numbers. 

Additionally i dont think its good to use random merge/IW buffering parameters here, we should set ones that won't make tons of files, force the use of compound file format, etc.

The massive amounts of logging should be addressed too.
