OK...

When I received my 128MB (cheapest) VPS from EV1, oomguarpages used were over 20,000 of 26,112. I was also getting red zone warning from the fresh default install. After noticing that that SpamAssassin and DrWeb were running, but not usable, I gleaned the following from around the web to remove them:

rpm -qa | grep "drweb" | xargs rpm -e
rpm -qa | grep "spamassassin" | xargs rpm -e

After a reboot, I was using a whopping 2,900 of 26,112 oomguarpages!!! :eek: Removing these unusable programs saved over half of my available RAM...

The system seems stable, and works fine now -- although I am still testing.

Has anyone else had a similar experience? Am I missing something?

(Why is this the default installation, when it is so unusable? Is there anything I should watch out for?)

Thanks!

thanks for the tip...
i just removed both things, rebooted the VPS, and now resource usage is much lower and there is a very noticeable increase in responsiveness.

Yea on my vps's i dont install those packages by default, ive noticed all my clients who install them submit a trouble ticket for resource issues and in the end its the same result of removing them.

i'd like to remove PostgreSQL now...

I don't even think that it's installed by default! There is support for it... But now installed.

This worked perfectly. I reduced the system load from 56000 to 4792...

Do you think that programs are needed to run the server? I´m referring to spamassassin and drweb. What are their function?

Ty Simon.

spamassasin is a spam scanner for your mail server and drweb scans for viruses, both are not needed and throw load way up.

Is there a safe way to remove PostgreSQL? I only use MySQL and don't need it.

Just ran the:

rpm -qa | grep "drweb" | xargs rpm -e

and

rpm -qa | grep "spamassassin" | xargs rpm -e

First one worked perfectly, the second command returned this messages for each e-mail address (e-mail address changed):

Delete spamassassin preferences from .qmail files for mailnames
Delete for "bob@bob.com"

Is that ok?

Yes. Simply use the same RPM command to find the package for Postegre.

paulius,
just tried but failed, there are dependencies:

error: Failed dependencies:
libpq.so.3 is needed by (installed) perl-DBD-Pg-1.21-2
libpq.so.3 is needed by (installed) php-pgsql-4.3.2-24.ent

Just remove the dependencies. Those are only the PostgreSQL packages for perl and PHP, so you don't need them if you don't want PostgreSQL installed.

cool, that did the trick

how can i remove dependencies ?

[root@plesk ~]# rpm -qa | grep "postgres" | xargs rpm -e
error: Failed dependencies:
libpq.so.3 is needed by (installed) php-pgsql-4.3.9-3.18.i386

thank you

Actually, Spam Assassin was exactly what forced me to double my RAM on my cPanel server!

It's a freakin' hog of RAM. I'm using 1GB now, and there have been no problems anymore.

My server was just running out of RAM before. :eek:

There's a way to do it right in WHM.

Two steps, actually:
1) Tweak Settings > Uncheck the following
- SpamAssassin Spam Filter
- SpamAssassin Spam Box delivery for messages marked as spam (user configurable)

2) Service Manager > Uncheck the following
- spamd SpamAssasin Server (if you choose to disable this, you should disable SpamAssasin in tweak settings as well) <-- Which we just did.


These are good instructions for people who prefer the not so scary GUI, instead of SSH.

Another option would be to use Google Apps for your Domain, and use Gmail -and its excellent spam filter- with your own domain name instead of *@gmail.com
https://www.google.com/a/
I am seriously considering this.

Many thanks for the advice!

We removed DrWeb and now Qmail doesn't restart.

Yeah, I did that here: http://phireme.com

Works great, but I need the whole webmail and pop3 thing going on with custom addresses.
