This sounds very much like PERIOD being set too low for your computer. This 
parameter is defined in /usr/local/emc/emc.ini, or generic.ini, depending on 
which run script you use.. The value is set at a fairly conservative 0.000025 
and should work with most 400MHz and faster computers. Even a P266 will run, 
but performance would be quite sluggish...

There are one or two motherboards out there that just can not provide adequate 
performance due to inherant design problems - Generally, anything that uses 
shared main memory for onboard video, certain i845/855 chipsets, and Geode 
processors all have "issues".

You could try increasing PERIOD to 0.00005 and see if avoids the freezing. 
Some additional information about your computer (make/model of motherboard, 
graphics card, etc) would help..
