Subject [jira] (CONTINUUM-2693) File handle leak with TCP connections in CLOSE_WAIT when using distributed builds
Date Thu, 22 Nov 2012 08:53:13 GMT
Brett Porter created CONTINUUM-2693:
---------------------------------------

             Summary: File handle leak with TCP connections in CLOSE_WAIT when using distributed
builds
                 Key: CONTINUUM-2693
                 URL: https://jira.codehaus.org/browse/CONTINUUM-2693
             Project: Continuum
          Issue Type: Bug
    Affects Versions: 1.4.1
            Reporter: Brett Porter


If you generate a lot of requests using the XMLRPC layer, such as when distributed builds
are active, it is possible for connections to stay in the {{CLOSE_WAIT}} state until they
are garbage collected. On a busy server with the default file limits, this can result in a
{{IOException: Too many open files}} error.

The workaround is to increase the limit of the files for the user running Continuum. However,
the XMLRPC layer should manage the connections better to avoid them getting into this state.
