There have been multiple threads over the last two years about the exact 
same 'vmstat 1' results, and no one has ever come up with a logical 
explanation as to why it occurs.

Of the several (probably hundreds) of posts in the past, it does not 
seem to be a linux distro issue, and stopping zaptel always removes the 
symptom.

It seems the majority of folks that were involved with this in the past 
'assumed' the results were what was impacting fax through the TDM400. 
But, don't think anyone proved that.

No other guesses at this time.
