[squid-users] Re: squid process offen restart by itself

i created a vm with 3 cores to test 1core frontend and 2cores backend.

there are my config files:
access.conf
<http://squid-web-proxy-cache.1019090.n4.nabble.com/file/n4662359/access.conf>
backend.conf
<http://squid-web-proxy-cache.1019090.n4.nabble.com/file/n4662359/backend.conf>
common.acl.conf
<http://squid-web-proxy-cache.1019090.n4.nabble.com/file/n4662359/common.acl.conf>
frontend.conf
<http://squid-web-proxy-cache.1019090.n4.nabble.com/file/n4662359/frontend.conf>
squid.conf
<http://squid-web-proxy-cache.1019090.n4.nabble.com/file/n4662359/squid.conf>

the cache.log of fronted shows:
