Weird bbm issue/question

Hey everyone

I didnt really know which place would be best to ask this but...

BBM has been downloading data over my wifi constantly for the last 4 hours, does anyone have any idea whu it would do this?
Also, System is using 40% CPU.

I have 4 BBM contacts and no groups... I have seen my Z30 do this before, but it would be nice to know why.

Thanks in advance

A friend of mine had this same issue.
Unplug your router. Leave it off for a few minutes and them plug it in and start again. Monitor your usage. It was the router in her case.
