I've got an Avanti (AS200 4/166) and an Alcor (AS600 5/300) on RH5.2 running as Squid siblings (I have another i386 sibling). Traffic are pretty heavy on the network I/O, cpu load is low to medium.
My problem is that for the Alpha squids, ping time on the local subnet increases with time. i.e. network throughput slowly but surely decreases; from a ping RTT of 3ms to 3000ms from another PC on the same subnet. This 1000 fold degradation typically takes from a couple of hours to maybe a day depends on traffic. After which the alpha boxes are totally inaccessible either via ftp or telnet. This sucks because one of them is my main ftp server!
The workaround is to do a network reset (S10network restart), and things are zippy again (for now)! I'm sure this behavior is alpha-related as the i386 box has not exhibited this behavior.
I'm now running a daily cronjob to reset the network! This is not to say the least embarrasing as this installation is supposed to show off to my colleagues and management the stability and reliability of Linux running backend services unattended....
Anybody seen this? Help!
BTW, I'm running 2.2.2pre4 as 2.2.2 doesn't compile. I've heard that 2.2.2-ac4 does compile on Alpha but I haven't tried it yet...
