DEAD/REVIVED the yoyo effect

Hello,

I regularly get messages in my cache.log such as

97/04/30 14:45:21| Detected DEAD Sibling: lyrebird.cc.uq.edu.au/80/3130
97/04/30 14:45:52| Detected REVIVED Sibling: lyrebird.cc.uq.edu.au/80/3130

The siblings share the same 100Mb ethernet and while both are busy,
neither is overloaded. The squid processes do not die. There just seems
to be some confusion as to whether they are up sometimes.

I also get these errors for local parent caches. For overseas parent
caches, it just registers as 'down' the whole time.

Is this indicative of some gross misconfiguration on my part?

I'm running squid-1.1.10 on DEC alpha 500's (Digital Unix).
