Re: Squid memory consumption problem

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hey,

 

Squid 4 is tested on Amazon Linux 2.

I have tested it in the lat year.. and I believe that there is no reason to run a full set of tests now.

 

Squid 4 only needs a basic “dry-run” to make sure what you need to change in your squid.conf.

 

I do suggest to first run it whiteout any cache-dir for maybe an hour.

 

Do not go back to CentOS 7.

 

To my knowledge Amazon Linux 2 receives a better over-all support then CentOS 7.

 

From my tests in the past Amazon Linux 2 is faster and is a LTS distribution so you will have someone to contact in any case of trouble.

Compared to CentOS X which you will be in the grace of your own efforts and “google foo”.

 

I believe that you would not want to find your self in a situation which you try to contact upstream RH for help.

 

Feel free to send me or the mailing lists any email you want.

I will try to at-least read them if I cannot respond on the spot.

 

Eliezer

Hi,

 

Thanks for providing the rpm information but I was having some questions as per my last email.

==============================================================================

Does it mean, Squid 4 is not tested on Amazon Linux 2, yet?

 

How much time, testing will take?

 

If it will take time , then I am thinking to change the Operating system to Centos 7 from Amazon Linux 2 and then install Squid 4?

## The last email got corrupted for some reason so..

 

First save the existing config files.

 

The RPM files are at:

https://1drv.ms/u/s!AoiLG1Jyh7JqoiBbOtBMb9wuAfjS?e=9XeXCS

 

You will need to install:

perl-Crypt-OpenSSL-X509-0.1-1.amzn2.noarch.rpm

 

 

It’s a dummy recursive package that installs basic dependencies.

You will not be able to install the squid-helpers packages without it.

 

Then install the RPM’s:

squid-4.12-1.amzn2.x86_64.rpm

squid-helpers-4.12-1.amzn2.x86_64.rpm

 

If you have installed squid RPM’s from other sources/repositories you will need to first uninstall/remove then and only then install the ngtech RPM’s.

 

If for any reason you need the sources for the RPM’s take a peek at:

https://github.com/elico/squid-docker-build-nodes

https://gist.github.com/elico/5fa3050ed1a7247fbf2f6810c74933cc

Hi,

 

We have two squid servers running in our environment.

 

  1. Squid Cache: Version 4.2-20180806-r6d8f397 running on CentOS Linux release 7.7.1908 (Core)---- Its running perfectly with no CPU and Memory issue

 

  1. Squid Cache: Version 3.5.27-20180318-r1330042 running on Amazon Linux 2 --- It’s not running perfectly with high CPU and Memory issue

 

I think you are right, please provide the Squid rpm version 4 for Amazon Linux 2 Or link to download.

I have tested v4 to work properly on Amazon Linux 2 in the past.

If RPM’s are needed, let me know.

I would start by making sure that you are not suffering from Squid bug

#4005: https://bugs.squid-cache.org/show_bug.cgi?id=4005

 

After that, if you are sure that there is a memory leak, then I suggest

upgrading to v4 (or v5) as the next step. IMHO, it is unlikely that

somebody would volunteer to triage a v3.5 memory leak these days.

 

 

HTH,

 

Alex.
