Hi, I've run into problems after upgrading 3.0.STABLE19 (installed from
packages) to squid 3.1
I'm running amd64 8.0-RELEASE FreeBSD, with squid as accelerated proxy.
3.0.STABLE19 runs almost flawlessly. I'm getting 'Select loop Error' every
second:
2010/05/21 14:37:34| Select loop Error. Retry 1
and these errors once in a while in my cache.log:
2010/05/21 14:39:14| comm_old_accept: FD 14: (53) Software caused connection
abort
2010/05/21 14:39:14| httpAccept: FD 14: accept failure: (53) Software caused
connection abort
I've never ran in such problems on Debian Squeeze (also with squid3.0), so I really don't know if I could ignore them.
I have successfully tested 3.0.STABLE19 on FreeBSD with 2500hits/s
Wow. Sure thats hits/sec and not hits/minute?
The 'extreme' setups of Squid-2.7 only reached 990req/sec.
After a while I tried to upgrade to the newest version of squid I've tried squid-3.1.3 from ports, and squid-3.1.0.13
from packages. Both versions after handling few thousands of requests are stopping serving on specified port.
Here is my configuration squid listens on 2 ports:
netstat -an |grep LISTEN
tcp4 0 0 *.8080 *.* LISTEN
tcp4 0 0 *.80 *.* LISTEN
'All' request goes to :8080, I configured port :80 only for testing. After few thousands of requests to :8080, squid stops
handling requests coming from that port. If I telnet to :8080 my connection is closed instantly, but If i send request to
:80 everything is fine.
Here are excerpts from cache.log, after I saw that squid doesn't serve anything
I stopped it:
2010/05/20 12:09:56| Preparing for shutdown after 7460 requests
2010/05/20 13:00:19| Preparing for shutdown after 8843 requests
2010/05/21 14:10:37| Preparing for shutdown after 9963 requests
While trying two 3.1 versions of squid I also saw 'Select loop Error. Retry 1'
FWIW; the only other occurrence of this particular "Select loop Error"
reported in recent years was found to be due to broken NIC drivers.
The behaviour sounds very much like some such bug has been hit, or maybe
a limit on the open ports per IP.
