Subject [jira] [Created] (HTTPASYNC-30) Connection already open error on some requests
Date Mon, 12 Nov 2012 20:49:12 GMT
Mark Greene created HTTPASYNC-30:
------------------------------------

             Summary: Connection already open error on some requests
                 Key: HTTPASYNC-30
                 URL: https://issues.apache.org/jira/browse/HTTPASYNC-30
             Project: HttpComponents HttpAsyncClient
          Issue Type: Bug
    Affects Versions: 4.0-beta3
            Reporter: Mark Greene
            Priority: Minor


I apologize in advance for not providing a unit test or steps to reproduce but I've only seen
this is the first time I've seen this happen in my production environment.

The only context I can really provide is that out of the roughly 7 million async http calls
a day my app makes is this first time I've seen this. Additionally, the URI I was attempting
to hit had made successful calls leading up to the error. The status code that is to be returned
from this URI is 204.

Stack trace is:
 java.lang.IllegalStateException: Connection already open
