We have had our first instance of serious filesystem corruption on an EX4200 running 10.3R1.9. I am hopeful that the new-fangled stuff in 10.4 will stop these incidents from causing switches to reboot into an un-usable state requiring a reinstall from USB. :-/
In other news, we also observed an M160 with two REs (one in the process of upgrading from JUNOS 6.2) exhibit an interesting new failure mode. The second RE incorrectly reported its CPU Temperature as about 800 million degrees, which caused the master RE's chassisd to spawn children emitting warnings about 3 times each minute. Unfortunately, chassisd was not wait(2)ing on these children after they exited. This produced additional console warnings about the maximum number of processes for uid 0. After about 15 minutes, there were enough <defunct> children of chassisd that the kernel process table was full, resulting in a kernel panic and automatic reboot. We had to remove the second routing engine to prevent it from happening a second time. IRB on MX80 10.4R4.5 appears badly broken, too. Configuring a bridge-domain with one untagged/"access" interface and one dot1q-tagged sub-interface, plus an IRB interface for layer-3, is a pretty good way to waste a couple hours troubleshooting the router. It works fine most of the time, and all looks well in the PFE console; but a few times per hour the Bridge-Domain simply stops forwarding any traffic, while the IRB loses its ARP entries. This fault sometimes lasts long enough for BGP to drop. -- Jeff S Wheeler <[email protected]> Sr Network Operator / Innovative Network Concepts _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
