Workaround: On the computer that hosts the BlackBerry MDS Connection Service, in C:\Program Files\Research In Motion\BlackBerry Enterprise Server\MDS\Servers\instance\config, in the rimpublic.property file, add the following property: AsClientConfig.ChunkSizeKBytes=1024.
If you import a self-signed certificate into the proxy server keystore, users cannot install an application that the BlackBerry MDS Connection Service accesses using HTTPS as the secure status of the certificate is not maintained. The users see an HTTP 500 error on the device. (DT 344187)
Workaround: Use certificates that certification authorities sign.
