Is there any update on this?  I have a client experiencing the same issue. 

 

They have a very small installation, but periodically see processor utilization get pegged at 100%.  I've narrowed it down to specific times, and there's a recurring pattern in the IIS log's pointing to LiveSupport:

 

cs_method                                                                                                            cs-uri-stem

 

/CuteSoft_Client/CuteChat/Support-Visitor-monitor-crossdomain.js.aspx	_temp=1239932785147&Type=VISIT&CCCustomerId=afc33d00-7496-4254-5250-615e356acb08&Referrer=http%3A//imleagues.com/Members/Log.html

This pattern repeates for 3 different source browsers (based on IP address).  It seems to coincide with one of the operators logging in.  They donot see any error.

 

 Any advice?
