Hi Problem is that it's VRRP and OSPF used together. Some sitation interfaces flapped and VRRP changed states very quickly. OSPF can't injection VRRP's virtual IP address to routing tables so OSPF going to broken (ipsord die) sometimes fwd die. This configuration isn't supported by Nokia. First IPSO when this configuration is supported is IPSO 3.8B31. There is some where a scripts which may be help you at some scenarios... http://www.deathstar.ch/security/fw1/OperatingSystemIPSO/files/monitor-script.pdf and other which should shut down OSPF when platform isn't master Original is made by Nokia, but i think you can't found it from Nokia support site. Symptoms is high CPU load, coredumps, crashs etc. so Nokia support site is detailed explanation why your systen can't work. I recommed at you upgraded your system or tried found this kind of scripts which are above.....some of command are version depend ;-) and them aren't officially supported. Remember when You upgraded vrrp rules changed lot. -- Riku Sorry about top posting M$ rulez ----- Original Message ----- From: "Andrew Shore" <andrew.shore@holistecs.com> To: "Pablo Hauser" <pablohauser@yahoo.com.ar>; "Markus Wernig" <listener@wernig.net>; <firewalls@securityfocus.com> Sent: Tuesday, January 18, 2005 10:28 AM Subject: RE: debug checkpoint fw-1 on nokia ipso A couple or so years ago I had a similar problem with an IP330. For about two weeks the unit exhibited similar problems (although we had only one, no fail over) Finally after much head scratching the unit went pop and never worked again! Perhaps it is some kind of hardware issue? We never got to the bottom of it, ours was under warrantee and the replacement was fine. Sorry, this probably won't help.

Sometimes happened to me that \var\fw\log\ahclientd.log "tilts" and continues non-stop growing for some reason, and that causes similar troubles as yours, but it doesn't stop by itself as in your case... __________________________________________________ Pablo D.

("upgrade", i hear you say. yes, we're at it, but it will take more time than we have to solve this) Symptoms: At random times the box gets 100% loaded, i.e. - a constant 0% cpu idle time reported by vmstat (with 99% in system, 1% in user mode) - shell is almost unresponsive (charactes on prompt echoed at a rate of one per 30 seconds, commands never returning, login taking about 10 minutes) - box practically stops forwarding any traffic - interface throughput drops to zero on ALL interfaces (measured in retrospect on switch and in ipso interface statistics) - box takes about 3 seconds to reply to icmp echo-request - box stops sending out OSPF and VRRP packets, resulting in failovers and OSPF recalculations, then occasionally sends one out, resulting in another session of failovers and routing convergences. Then, after 10-30 minutes, suddenly all returns to normal (80% idle), nothing in the logs except for the OSPF messages from ipsrd. On one occasion I managed to get a "ps auxw" through, and it showed monitord using 10% cpu and fwd using 8% cpu, all other processes were using below 0.1%. But I assume this only showed userspace processes.
From all that I see, it's the kernel using all resources, or a hardware
fault. Now: is anyone aware of a tool or method to get more information about what is causing this load? Has anyone heard of an attack that might cause these symptoms? Can anyone remember a bug in that version of fw-1/ipso that might result in this behaviour? Generic observations? I'd be grateful for any pointer. thanks /markus
