limit number of child processes

[philkry]

hi there!

i want to install zimbra on my server.
on my test-system i saw a lot of child processes of spamassassin, amavis, clamav and all the other components.

well on my real system there will be only 4-5 users.
so this is gonna be overkill

how can i limit the number of processes of all components to 1-3?

thanks in advance

bye

Hi

Welcome to the forums.

I don't think you'll notice any degradation on your system, are you having any problem after installing Zimbra? Does your server meet the minimum specs?

[philkry]

no it doesn't meet the minimum specs.

it is a p3 800mhz with 256mb ram.
zimbra slows down my system extremely. no chance to start any other services.

so u don't think the system load will be decreased by limiting the child processes to 1-3?

[phoenix]

No, I don't think the number of processes is the problem it would be the amount of RAM that's way too low. I'm not an expert on tuning Zimbra or linux, maybe one one of the zimbra guys might have something that may help.

[philkry]

ok.

i allready removed zimbra-logger, zimbra-spell and zimbra-snmp.

any other tuning ideas?

edit amavisd.conf.in, cut down max_processes to 2 or 3 (NOT 1 - that'll kill mail delivery)

edit /opt/zimbra/postfix/conf/master.cf, look for the smtp-amavis line - cut the 10 on that line down to whatever max_processes for amavis is set to.

Cut down zimbraLmtpNumThreads to a lower value

man 5 postconf - many throttling options there.

Make sure the logger stuff is gone from the crontab, too.

I have a PII 350 Mhz with 768 MB of RAM with Fedora Core 3.
On that system I have VMware Server with 400 MB Ram with Fedora Core 4 with Zimbra. The only thing I did was tune how often the logger runs (crontab).

So as far as I can tell the main issue you have is the amount memory.
