Re: Our loner squid retrieiving unreqested mystery data

* No evidence, I don't keep the access logs, I send them to
/dev/null. I have been running Squid/Linux for a long time with not
so many problems.
* I graph Squid's SNMP variables using MRTG & a formula that Henrick
Nordstrom gave me when I was asking how to do such things. Normally
the traffic coming in is less than or equal to the traffic going out
but on both occassions MRTG showed Squid downloading at the maximum
rate of our bandwidth unrelentlessly. Some clients reported that
their downloads were down to 300 k (where normally they are getting
about 5.5 K) and all other evidence available points to Squid (ie none
of the other machines showed corelating traffic).

I fully accept that this may not be a difficulty of Squid but I would
like some suggestions, if the advanced users on this list are feeling
magnaminous enough, as to what might explain the behaviour &/or if
anyone else has had the behaviour too.

Thanks Alex,
Marc :-)
