In the log of the squid proxy cache server me and some warnings are coming out every time I leave the proxy fails to resolve normally, it starts to take to resolve.

WARNING: no_suid: setuid(0): (1) Operation not permitted

I solve the above problem by restarting the squid proxy server, but after a while the same thing happens to me.

I was looking at the logs and I see other warnings but nothing abnormal.


My OS is Ubuntu 12.04 Server 64bit and Squid 3.4.4.

Parameters to compiler:

./configure '--build=x86_64-linux-gnu' '--prefix=/usr' '--includedir=${prefix}/include' 
'--mandir=${prefix}/share/man' '--infodir=${prefix}/share/info' '--sysconfdir=/etc'

/run/' '--with-filedescriptors=65536' '--with-large-files' '--with-default-
user=proxy' '--enable-linux-netfilter' 'build_alias=x86_64-linux-gnu' 'CFLAGS=-g -O2 -fPIE 
-fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security -Werror=format-
security' 'LDFLAGS=-Wl,-Bsymbolic-functions -fPIE -pie -Wl,-z,relro -Wl,-z,now' 
'CPPFLAGS=-D_FORTIFY_SOURCE=2' 'CXXFLAGS=-g -O2 -fPIE -fstack-protector --param=ssp-buffer-
size=4 -Wformat -Wformat-security -Werror=format-security'  'build_alias=x86_64-linux-gnu' 

And add user proxy:

sudo adduser --system proxy

The squid server proxy normally rises and can navigate, I spent a few minutes or hours, starts to get slow and I always get the above error.

My idea of ​​putting problem is the problem of cache with user privileges on the proxy.

Thanks in advances.

What OS, what user are you running squid under. Give more details. It is a permissions problem of some source, so track that down. – Zoredache Mar 19 '14 at 21:28
I'm updated the ask. – Jose Carlos Ramos Carmenates Mar 24 '14 at 3:35
