Ken, David, Guess we are all on the same page afterall i.e Dominic should grab the crashinfo files and contact his maintenance service provider TAC.
To close, if IOS crashes as a result of a 'SegV exception', the cause is a software bug. Unfortunately, any other diagnosis would be a misdiagnosis. eninja :-) www.multiven.com - simple, efficient & affordable maintenance for all networks™ On Nov 11, 2010, at 2:27 PM, "Matlock, Kenneth L" <[email protected]> wrote: > Exactly! > > The only way to determine 100% if it's a hardware problem or software problem > is to either go through TAC for a bug scrub, try a known good version for the > features you are using, or go through the code one line at a time and figure > out why the SegV happened. > > I was just pointing out that it's impossible to know with 100% certainty if > it's software or hardware corrupting that memory location.
