Dear All,
I got 2 query which are as follows

*1. How to disable logging of few ACLs ? for example I have below ACL which
I trust and I do not enable caching *

[root at proxy squid]# cat no_cache_domain.txt
.ubuntu.com
.googlevideo.com
.googleapis.com
.googleusercontent.com
.windows.com
.windowsupdate.com
.kaspersky.com
.copernicus.eu
.praction.in
.webwerks.in

# and in squid.conf
acl no-cache-domains dstdomain "/etc/squid/no_cache_domain.txt"
cache deny no-cache-domains

*2. Kernel Out of Memory ( I currently have logrotate on weekly basis ),
how this issue can be fixed it runs nearly 12 hours without any error*

Log error is as follows:

May  1 08:45:20 proxy kernel: Out of memory: Kill process 24384 (squid)
