Subject [jira] [Commented] (HTTPASYNC-36) SocketTimeoutException can result in failed() being called multiple times
Date Fri, 06 Jun 2014 18:48:01 GMT

    [ https://issues.apache.org/jira/browse/HTTPASYNC-36?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14020208#comment-14020208

yaping liu commented on HTTPASYNC-36:
-------------------------------------

I'm using 4.0 GA, and having issues happening @BaseIOReactor:sessionTimedOut, actually my
request just got in a couple of milliseconds, and it's got timed out where my socket timeout
is set to 10 seconds, so this immature SocketTimeoutException is throwing out within just
a couple of milliseconds. I feel that there is a race condition, can it when it's returning
the connection from the pool and when the selector is iterating the keyset?

> Appears to be a race condition, so I am having trouble duplicating, but we have observed
the failed callback method being called twice for a single request that timed out.
> Following stack trace was logged twice for a single request:
