To chip in here: over the last 6 weeks we had two crashes on a Cat6k Sup720-3B. Device was stuck in rommon afterwards; "reset" followed by "boot" hung the box, so we had to resort to full power down / power up. Did a reseat of the sup after the first crash, but it crashed again within two weeks after that. About the same conditions as in your case: IOS SXI2a, "software fault", crashes happened while the temperature was changing a few degrees. So it's either: * a software bug that we didn't hit for several months and then two times in a short period of time (and only on one of our two parallel routers) * temperature-sensitive hardware issue * other hardware failure Does that change your perception of the odds? ;) Regards, Jeroen van Ingen ICT Service Centre University of Twente, P.O.Box 217, 7500 AE Enschede, The Netherlands _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
