Hi All, I have a strange issue. We are using a OpenBSD 3.9 box running on an AMD64 CPU. Its doing BGP with our upstream provider and has some basic pf rules.
Occasionally, the network slows to a crawl. I setup some external monitoring, and while a few simple HTTP checks of boxes on our network normally take a second or 2 (from 2 separate locations outside our network), this just went up to over 100 seconds and was only resolved by restarting the box. I'm learning this stuff, so am super keen if a) this is normal behavior (I'm guessing not) and b) how can I work out what is causing the problems? I've checked messages, and there is nothing strange in there (just some ftp-proxy 'client reset connection' and 'server refused connection' messages) and daemon (a few BGP updates not many). On restart, I get a flood of BGP updates. Where should I be looking? Should I just restart bgpd next time or does this seem like something else?? Any advice would be greatly appreciated! Cheers! Karl
