Darn. The function name and other symbols have been stripped out of the
squid binary. The app can;t generate any useful traces.
You will need to try and replicate the problem in a squid built with
debug symbols still inside.
My settup
<*> Squid Cache: Version 2.7.STABLE6
configure options: '--enable-async-io'
'--enable-icmp' '--enable-snmp'
'--enable-cache-digests' '--enable-follow-x-forwarded-for'
'--enable-storeio=aufs,ufs,null,diskd,coss'
'--enable-removal-policies=heap,lru'
'--with-maxfd=65535' '--disable-ident-lookups'
'--enable-truncate' '--enable-linux-tproxy'
'--enable-linux-netfilter' '--enable-large-cache-files'
<*> Kernel 2.6.31.13
FWIW: linux kernel 2.6.3* do not support TPROXY version 2 (which is the
version in squid 2.7).
For TPROXYv4 you will needed squid-3.1 or later.
