I have a strange issue regarding the Mobile Management and nginx 1.3.1 (as a reverse proxy) on a RHEL 5.8 and the Mobile Management is running on Windows 2008.
Main issue is opening attachments on ipads/phones (iphones or windows phones), which was not a problem until we added more users to the MDM. After adding about 400 more users, emails with attachments are not downloaded to the device, a error message states "This message has not been downloaded from the server". Text file attachments seem to be opening fine, but not pdf's.
In the Nginx (reverse proxy) logs, it states: upstream sent invalid chunked response while reading response header from upstream.
But, after the mdm service is restarted on the Windows 2008 server, the attatchments download fine for about 15 minutes, then the issue returns.
Any advice would be appreciated.
