DEAD PARENT/SIBLING detected falsely? (was: two squids on the same machine)

Hello,

I finally got two squids working on the same machine routing each
through different (ISDN/PPP) interfaces (different ISPs). Both squids
neighbor each other. The problem is that after a while one or the
other squid detects a DEAD PARENT and a DEAD SIBLING which is the
other squid on localhost! This would mean that the other squid is dead
which is definitely not the case. I can also ping the parent after
this message is detected. Below is a debug 9 trace which shows that
the death detection comes with no delay after the icp send. The dead
timeout should take a while (20 icp requests), shouldn't it? This is
squid 1.0.10 on a Linux Box 2.0.14.

Thanks for help,

Dirk
