Asankha C. Perera resolved SYNAPSE-188.
---------------------------------------
Resolution: Fixed
Assignee: Asankha C. Perera
Fixed this and SYNAPSE-168 which is almost the same
> 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
> Assignee: Asankha C. Perera
> Fix For: 1.1.1
>
>
> 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?
