Hi,
In my cache.log i am seeing one error: "page faults with physical i/o:
1" other than that nothing on this box has changed.
For my firewall i'm using pf, and i use an rdr pass rule to redirect any
internal lan traffic to the router's squid port, this has worked fine so
far.
Would the core file be helpful?
Here's my squid.conf file, thanks a lot.
Dave.

Hello,
This is a strange one. I've got a FreeBSD 6.2 router with squid on it
for transparent proxy. It has been working fine, until about 3 days ago
when i noticed one of my internal machines wasn't completing an http
transaction, in this case downloading of it's ports index. The connection
would start out extremely slowly and eventually timeout then giving an
error about a truncated file. I checked my firewall, hard disks, debug
logs, messages everything, couldn't find any error msgs or anything
obviously wrong. This morning an internal machine, this one a centos box,
began failing with it's yum updates, giving timeout errors on retrieving
rpm files from http sites. Again, i ran the log checks, didn't see
anything. So, i next checked the firewall, nothing in debug.log or
messages, but in the /usr/local/squid/logs directory i found two things.
The first was that the failed transactions were all returning http
response code 206, timeout? The second was that i had a 43 mb core file.
I shut down squid, turned off the transparent redirect rule in my
firewall and everything started working normally. If this core file is
useful in debugging i'd like to know what to do or where to send it, i
can post it on a web page if interested. I'd appreciate any suggestions.
The squid version used is 2.6.13, memory and cpu usage during the
times in question are not even moving, this system is not in any way
heavily loaded.
Hi Dave,
Are you sure that you did not modify anything substantial in the past 3
days? Firewall rules, sysctl tunables in your FreeBSD box?
The core file suggests that your Squid might have crashed. Are you sure
that there is nothing in your cache.log?
Which firewall do you use to do transproxy? Can you show us your relevant
firewall rules?
Also posting your squid.conf might help. How many users are accessing your
cache normally? If you manually use your proxy server in your web browser,
does it help speed up the web requests?
Thanking you...
Any suggestions appreciated.
Thanks.
Dave.
