It certainly can, since recording the call causes disk I/O as the audio 
is written out. In addition, Monitor is more prone to this problem than 
MixMonitor is, because Monitor's call recording is done in the same 
thread that handles the call's audio normally. If you switch to 
MixMonitor, you'll probably have better results, unless your system just 
can't handle recording the call without overloading its CPU.
