Re: [foxboro] XP Workstations - 72 day lockup?

OK,

I haven't heard of that, but I sort of believe you because of the following...

this has nothing to do with XP, BUT there is a known bug in some of 
the Allen Bradley CNB(R) modules that causes them to freeze every 
70.96 days.  There  is a Rockwell Note on this problem P155242786 
there is another for a CNB(R) failing after 497 days Rockwell Note 
A120646851 both from the Rockwell Knowledge Base.  An AB  firmware 
upgrade fixes the problem.  Rumor has it that some number gets 
exceeded by a free running counter.  ( I can't confirm this.)

So while I haven't heard of XP failing after this length of time, it 
appears there is a magic number that needs to get reset after ~71 
days on some items.

Perhaps you're not crazy after all, and even if you are, a little 
paranoia never hurt anybody.

Regards,
David
