I have a client who experienced this as well on a pair of 7206VXR's. The two routers rebooted themselves due to memory parity error. The "cosmic radiation" was kind enough to cause the reload in the wee hours so no harm done.
What's weird is that we have six 7206's in the same cabinet but only two experienced the problem. The two afflicted routers just happened to service the same group of subnets (HSRP peers)...kinda strange. TAC dude wanted me to remove and re-seat the memory in the routers. He said that if the problem happened again that they'd replace the memory. I opened up one of the routers to find that the memory is not only secured by retaining clips on each side but it also has a screw through it...I didn't bother on the other router. (knocking on wood) It has been several months since that happened and we've run clean since. If you're seeing this on a brand-new box, I'd guess infant mortality. Perhaps you can convince TAC to send you some new memory if you're still fighting this problem. If new memory still has the problem then you'll need to look at "environmental" conditions in your data center - e.g. grounding, heat, a lot of EMI, etc. ""Farooq Ali"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Hi all: > > I am a giga-lurker on this list and over the past 3 years have benefitted a > lot.
