Hi all. We've had a bit of bad luck lately with a couple of NPE-G1's suddenly reloading due watchdog timeouts.
In all cases, we've been running 12.2SRC (first SRC1, and currently SRC2). Without any crashinfo generated from the reload, Cisco say this points to a hardware problem. We initially experienced this on an NPE-G1 built in 2003 (the chassis might have been built about the same time also). But then it also affected NPE-G1's built in 2005, as well as 2007. We swapped out one of them that has been rebooting more frequently (once every 2 months) with a 2007-model NPE-G1. This just failed a few days back, same reason. This morning, yet another 2007-model NPE-G1 also experienced the same problem. This one had never done this before. It also is installed in a 2007-model chassis. The following is consistent: * The watchdog timeout reset is affecting only our NPE-G1's. * All NPE-G2's and 7201's, running SRC2, are not affected. * It affects both old and new NPE-G1's. * It affects both old and new chassis'. * All routers are running 12.2(33)SRC2. We're going to open another case with TAC on this, but I feel this is going to be drawn out. It would have been easier if this affected either ONLY the old model NPE-G1's, or the new model NPE-G1's; because then we could either chalk it down to old boards or a bad batch (the 2007 models were all built to the same order). But since this is affecting both old and new, and the information suggests it's not software-related, it gets tricky. Aside from software, the only other thing that unites both the old and new chassis'/processors is PA-2FE-TX cards we bought for both the old and new models. Suffice it to say that before the older NPE-G1's were running SRC (they either run 12.3 mainline or 12.2S), we didn't see this issue. Appreciate any thoughts here. Cheers, Mark.
