Subject [jira] [Created] (SOLR-5427) SolrCloud leaking (many) filehandles to deleted files

Eric Bus created SOLR-5427:
------------------------------

             Summary: SolrCloud leaking (many) filehandles to deleted files
                 Key: SOLR-5427
                 URL: https://issues.apache.org/jira/browse/SOLR-5427
             Project: Solr
          Issue Type: Bug
          Components: SolrCloud
    Affects Versions: 4.5, 4.4, 4.3
         Environment: Debian Linux 6.0 running on VMWare
Tomcat 6
            Reporter: Eric Bus


I'm running SolrCloud on three nodes. I've been experiencing strange problems on these nodes.
The main problem is that my disk is filling up, because old tlog files are not being released
by SOLR.

I suspect this problem is caused by a lot of open connectins between the nodes in CLOSE_WAIT
status. After running a node for only 2 days, the node already has 33 connections and about
11.000 deleted files that are still open.

I'm running about 100 cores on each nodes. Could this be causing the rate in which things
are going wrong? I suspect that on a setup with only 1 collection and 3 shards, the problem
stays hidden for quite some time.
