If backend https service is down, frontend service https gets low level problem
that destabilizes non-blocking transport
------------------------------------------------------------------------------------------------------------------------
Key: SYNAPSE-188
URL: https://issues.apache.org/jira/browse/SYNAPSE-188
Project: Synapse
Issue Type: Bug
Affects Versions: 1.1
Environment: JDK6 RHEL3
Reporter: Paul Anderson
I use PHP to send POX via SSL. Synapse then sends to the backend Geronimo, SOAP
over SSL. But if the backend is down, I get transport errors.
Maybe the error is related to the byte buffering issue that was fixed recently
(thanks!) to get Synapse working with PHP SSL input.
Maybe if I switch off NIO it will be more stable?
