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
