I think its an internal axis2 issue in that the httpclient call needs
to invoke closeIdleConnections() . I've battled CLOSE_WAIT issues a few
times and I think I know what's happening. If you attach your source
here, and attach your netstat output along with how long the CLOSE_WAIT
condition lasts, I'll try and reproduce the error and then try to fix
it.

Is this an issue with ServiceClient's
finalizeInvoke() method not properly cleaning up the connection? Would
I experience the same socket resource starvation with Axis2 if I reverted
to a simpler implementation using the ServiceClient.sendReceive() method,
rather than the OperationClient.execute() method?
Thanks,

This is a known issue:
http://issues.apache.org/jira/browse/AXIS2-935
There is a patch submitted. If you could attach your test case to it
I'll take a look at the patch.
