Also issue can be resolved by tunning BES server with next registry keys:

HKLM\Software\Research In Motion\Blackberry Enterprise Server\Dispatcher
HKLM\SOFTWARE\Wow6432Node\Research In Motion\BlackBerry Enterprise Server\Dispatcher
MaxUsersPerAgent

HKLM\Software\Research In Motion\Blackberry Enterprise Server\Agents
HKLM\SOFTWARE\Wow6432Node\Research In Motion\Blackberry Enterprise Server\Agents 

MaxMailboxesPerSession

HKLM\Software\Research In Motion\Blackberry Enterprise Server\Agents\NumAgents
HKLM\SOFTWARE\Wow6432Node\Research In Motion\Blackberry Enterprise Server\Agents\NumAgents
MaxUsersPerAgent

Where HKLM\SOFTWARE\Wow6432Node\ is for x64 systems.
