Re: Parity errors and Cosmic radiation! [7:46282]
Digging a hole might not be such a good idea. According to an IBM article, they claim that radon gas can also produce the problem. So I guess you shouldn't put equipment in the basement either. http://www.research.ibm.com/journal/rd/401/curtis.html - Original Message - From: Frank Merrill To: Sent: Tuesday, June 11, 2002 9:54 PM Subject: RE: Parity errors and Cosmic radiation!

This is what TAC will most often referance when you experience a parity error: http://www.cisco.com/warp/public/122/crashes_pmpe.html Dave R. Benjamin Kessler wrote: 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]...

An easy test just reading those questions.. Need to refocus..make myself schedule the lab..why do I exist?isn't there a RFC answering that?.why don't I read more MPLS RFCs instead of sleeping 5 hours a night?why haven't I memorized Halabi yet?.still haven't seen Episode II yet..

Ha!! I like it!! About 6 weeks ago we were having many problems installing 6509's for the State of Colorado, went through 7 supII cards before we got two that would even synch up correctly, and I half jokingly blamed the bizarre behaviour on the altitude!!!
