Overview
BlackBerry Dispatcher passes a packet larger than 64 KB to the BlackBerry Router. The BlackBerry Router discards these packets, but also momentarily drops the Server Routing Protocol (SRP) connection to the BlackBerry Infrastructure.

When this issue occurs, the following event appears in the BlackBerry Router (ROUT) log:
