I see, but looking at the log again just now, it has lost the -vv, then 
it reminded me that another script had been run since I restarted 
fetchmail and it, sa-train-bayes was restarting fetchmail w/o the -vv.
so thats fixed now. And fetchmail is blabbering like an idiot, 20+ lines 
of output per new mail scan 120 seconds after the last one.  So now we 
wait.  Since the last such instance was 4 or so months back, it may be a 
while, but it will be easier to find since its now logging times again.

Thanks for the update Mathias.  Take care & stay well now.
