I'm getting a little bit frustrated about the subjects message (Send failed) on the production server. Until now everything worked fine (1 year) with the regular deploy mechanism I had but 5 day ago I just get the message Send failed for every RemoteService request, while the Ping is working fine.
The system is a PHP backend with Zend (newest), Doctrine 1.2 and using Flash Builder 4.0.x. I got down to the lowest level of Zend Amf (debugged line by line) but as I see there is no PHP issue, no DB issue and I have no more ideas where else to look for this issue.
the only thing I can think of is the Rewrite Rule is broken (because the server has been changed, but no version upgrade on the components). I'm not very familiar with that.
