Subject [jira] [Commented] (HTTPASYNC-39) SocketTimeoutException occurs too soon
Date Tue, 18 Jun 2013 10:54:20 GMT

    [ https://issues.apache.org/jira/browse/HTTPASYNC-39?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13686573#comment-13686573

Oleg Kalnichevski commented on HTTPASYNC-39:
--------------------------------------------

This has all the symptoms of a race condition but for the love of God I cannot see how there
could be a race given synchronized access to all internal structures of IOSession.

Is there a chance you could add logging to you app from the contrib package [1] and try to
reproduce the problem with logging turned on?

> In a highly concurrent environment, where SocketTimeout is set to 30,000 milliseconds,
we are often seeing a timeoutexception after only 0 or 1 or 2 milliseconds has actually passed.
> I get the impression that in the AbstractIOReactor timeoutCheck function, session.getLastAccessTime
is being called on the session before the lastAccessTime is set on the session for the current
session (ie. the lastAccessTime being retrieved is the time that was set on the session object
for the previous http session)
