Running Scientific Linux 6.6 (based on CentOS), compiled squid 3.5.5
with no errors.
Issue happens with both squid 3.5.5, and the newer 3.5.5-20150528-r13841.
Starting squid service and running for a while, any attempt to access a
website like www.nwfdailynews.com causes squid to crash and restart. The
associated squid log entries from the same time squid crashes, seems to
be several "TCP_SWAPFAIL_MISS" at that time:
1433608644.053 117 192.168.2.110 TCP_SWAPFAIL_MISS/200 17246 GET
http://launch.newsinc.com/77/css/NdnEmbed.css -
HIER_DIRECT/184.51.234.134 text/css
Other normal use including facebook and other website do not have any
problems, so it has to be something relating to this site setup causing
the crash. We are using this in a testing server for now but hoping to
roll out to production level used by a few thousand people.
These are the only modified entries in squid:
-----

# this port is what will be used for SSL Proxy on client browser
http_port 3129 intercept
https_port 3130 intercept ssl-bump connection-auth=off

#Also for log watching to check for errors, add these lines:
cache_log /var/log/squid/cache.log
cache_effective_user squid
debug_options ALL,0
logfile_rotate 10
cache_mgr myemail@xxxxxxxxxxx
pinger_enable off
visible_hostname A7750
# Uncomment and adjust the following to add a disk cache directory.
cache_dir aufs /var/cache/squid 10000 32 512

Let me know anything else you may need or suggestions.
