Hi
I am running squid-2.6stable4 in reverse proxy mode as a front end for a Microsoft exchange 2003 SP2 server providing outlook web access, outlook mobile access and active synch.
I am terminating the SSL connection between the internet client and squid at the squid server then establishing another https connection between squid and the exchange server.
The configuration is working well however I am getting lots of the following errors in my cache log.
2006/10/31 10:50:16| fwdNegotiateSSL: Error negotiating SSL connection on FD 16: error:00000000:lib(0):func(0):reason(0) (5/0/0)
2006/10/31 10:50:16| TCP connection to xxx.xxx.xxx.xxx/443 failed
No errors are reported by the client or in the access log and everything appears to working fine.
The memory usage of squid grows and eventually I get an out of memory error and squid is terminated by the kernel. This takes about a week to occur with the current usage of the proxy.
I upgraded from squid-2.6stable3 as I was seeing the same behaviour and hoped stable4 may have a fix.
The relevant (hopefully) sections of my squid.conf follow (hostnames edited)
https_port squid.exchange.proxy.ip:443 defaultsite=xxx.xxx.xxx.xxx \
cert=/etc/httpd/conf/ssl.crt/xxx.xxx.xxx.xxx_proxy.pem \
key=/etc/httpd/conf/ssl.key/xxx.xxx.xxx.xxx_proxy.key protocol=https
cache_peer exchange.server.fqdn parent 443 0 front-end-https=on \
ssl sslcert=/etc/httpd/conf/ssl.crt/emlcssurproxy02_client.pem \
sslkey=/etc/httpd/conf/ssl.key/emlcssurproxy02_client.key \
sslcafile=/etc/httpd/conf/ssl.crt/emlcsca.pem \
originserver proxy-only connection-auth=off no-digest login=PASS
Perhaps I have an incorrect setting in squid.conf which is causing the error? I have searched on the net for similar errors but have not found an adequate explanation yet.
I look forward to suggestions from the group. Please let me know if there is more information required to debug the problem.
Regards
