RE: [SQU] Select Loop Failed

I had this problem with one machine. I ran a script to bandaid it until a
new card arrived:

#!/bin/sh
ifconfig eth1 down
ping -c 1 some.address
ifconfig eth1 up
sleep 60

It was definitely a card/driver issue, though. I've been using Iexas
Instruments TLAN-based cards successfully since.

What you describe is more likely a network driver issue. If there are
network driver problems then Squid will get into trouble as well, in
some cases with the mentioned error message.

Try switching to another network card model or brand.

Problems similar to this have been experienced on Linux with
   * 3com vortex cards
   * Intel EtherExpress 100
   * Tulip based cards (built in Compaq server card)

Of the three the tulip cards have been the most stable, but then I
haven't used the other two models in quite some time now (a year or so).

In some cases messages are logged in /var/log/messages, sometimes not.
In most cases it helps to stop the network, unload the driver module and
start the network again.
