No this a physical box and we are using only for squid. We have 4 cpu’s and 16 cores.

How many CPU's and\or core's are on this machine? Is it a VM? How many users will be sitting behind this proxy? Depends on the above we can decide on the right approach.

squid-users@xxxxxxxxxxxxxxxxxxxxx Subject: RE: Crash: every 19 hours: kernel: Out of memory: Kill process (squid) Hello Eliezer, We are using OS "Redhat 7" and squid version 3.5.20. As of now we are not using any cache, we already commented out. You want me try using cache by uncommenting the following line.
# Uncomment and adjust the following to add a disk cache directory. #cache_dir ufs /cache/squid 10000 16 256 Thanks, Naresh -----Original Message----- From: Eliezer Croitoru [mailto:eliezer@xxxxxxxxxxxx] Sent: Wednesday, August 9, 2017 8:08 PM To: Cherukuri, Naresh;
squid-users@xxxxxxxxxxxxxxxxxxxxx Subject: RE: Crash: every 19 hours: kernel: Out of memory: Kill process (squid) Hey Naresh, The RAM you need would differ by the nature, hardware and couple other things about the nature of the machine. What you need is start from the bottom and move up. List for yourself the machine specs and your goals. It really helps to start from low ie the default 256MB ram cache and without any cache_dire and then see how it all moves on from there. For now you are getting to the 19 hours of up time and you need to overcome this so just start with a dry run of no disk cache at all and stick to squid defaults for the next 24-48 hours. Also what OS are you running?

I am getting a problem every 19 hours squid takes all RAM memory, then started taking swap in 20 minutes my swap is full. Then server side (OOM) is activating and killing all squid child's then finally killing squid
parent. Can someone help me how to address this problem? Why every 19 hours my memory is going to full? How much Ram do I need for following squid version?
