Apache atmosphere is sending an empty message every 5 minutes to the north bound. These messages contain a single byte, which is represented as a space character ' '. Is there any ability to disable those messages?

Hi Guys,
We are using Apach Atmosphere and several users shared the same concern,
where the north bound client (netcool in their case) is getting every 5
minutes a message with only one space. (This is NOT the X heartbeat
message).
Anyone know what this empty message (one space message) is? Any ability to
disable it?

Thanks,
Ori
