Subject [jira] Commented: (AXIS2-935) Connections are not properly released causing them to stick in the "CLOSE_WAIT" state and cause "Too many files open"
Date Mon, 10 Aug 2009 13:44:15 GMT

    [ https://issues.apache.org/jira/browse/AXIS2-935?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12741314#action_12741314

Haroon commented on AXIS2-935:
------------------------------

We are facing the same issue with Axis2-1.2 version when we use Axis2 as our Webservices client
to make WS calls.

Exception stack trace is : org.apache.axis2.AxisFault: Too many open files
Caused by: org.apache.axis2.AxisFault: Too many open files
Caused by: java.net.SocketException: Too many open files

I saw this post on AXIS2-2931 on the patch for this fix.  And it is mentioned that this patch
can be seamlessly applied in axis2-1.3 and 1.4

<https://issues.apache.org/jira/browse/AXIS2-2931?focusedCommentId=12676837&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#action_12676837>

However, since we are on Axis2-1.2 version, could you please let us know the approach for
fixing this issue, with minimum changes to the list of axis2 jars?

I'm doubtful, if I take the fix from <http://www.intalio.org/public/maven2/org/apache/axis2/axis2-kernel/1.3i3/>
and replace axis2-kernel-1.2.jar with axis2-kernel-1.3i3.jar, what other dependent jars I
might need to upgrade?

Any sort of help/guidelines on applying the proper fix to axis2-1.2 version is appreciated.

> It appears that org.apache.axis2.transport.http.SOAPOverHTTPSender does not properly
cleanup the http post connection after payload has been sent.
> The symptoms of this problem show up in `netstat` as literally hundreds of connections
in the "CLOSE_WAIT" state.  On a busy server this can cause the application to report exceptions
with the message "Too many open files."
> I looked in the source code for axis2 1.0 and discovered that in SOAPOverHTTPSender.java
the releaseConnection() is never called on the postMethod variable.  This seems to be a likely
candidate for the source of the issue.
> See SOAPOverHTTPSender.java:97-118
