[DogParkList] Odd issue with MLDX 5.03

[Steve Hellyer]

Larry if you get that again try open up Activity monitor and see if  
some other application is consuming CPU most of your CPU. You can sort  
the Activity monitor list by CPU by clicking on CPU column header.

You may notice an application running in that list called spindump.  
This OS application kicks in when as a running progress becomes  
unresponsive (hung).
Details here on what it does... http://developer.apple.com/documentation/Darwin/Reference/Manpages/man8/spindump.8.html

Console log is also a good friend here as you can usually see some  
type of trail of complaints from OS or applications.

This is not a solution but just some tools and techniques to gather  
more information on what might be occurring during these situations.

Lastly make sure your MicroHAM USB II drivers (FTDI serial chip) are  
up to date http://www.microham.com/index1.html
But you sound like a fellow who keeps things quite current and may  
have check this already.
