---------------------------------------
Hi [~chuanliu], I think this is not the root cause. I run restRetryProxy alone
and also get the timeout, this probably has nothing to do with socket leak.
Here is the error message.
{code}
public void run() {
LOG.info(Integer.toString(retryCount));
Assert.assertEquals(retryCount++, Server.getCallRetryCount());
}
{code}
