To free more memory I switch off collectinfo.pl . Another major user is miniserv.pl . Is there a way to lower that?

I have right now miniserv.pl run’s 4 times:

Sorry, I overlooked that… I attached the output of ps auxw to avoid horizontal scrolling…

The miniserv.conf is still there 4 times… [file name=ps.txt size=2879]http://www.virtualmin.com/components/com_fireboard/uploaded/files/ps.txt[/file]

Howdy,

You don’t have any swap enabled… so you have a rather small amount of RAM to start with (290MB it looks like) – and no swap to fall back on when that runs out.

ATM, you have 50MB of RAM available.

What I would do is work with your provider to get more swap space enabled on your box, which should go a long ways towards solving the issues you’re seeing.

However, you might also try implementing some of the goodies in this document for running Virtualmin on low-memory systems:

After I switched off collectinfo.pl and restarted the VPS I am at around 60Mb memory use - and no service died last night.

I will talk to my host about swap, not sure they offer it though.

25

Any Linux box can have swap enabled. If someone tells you otherwise, don’t use them for advise :slight_smile:

However, hopefully your VPS provider can suggest the best way to do that in your case, as I’m not familiar with their setup. There may be a partition already setup for handling swap, or if not you might need to use a swap file rather than a swap partition.

Either way, they should be able to help you out there.

and just in case, this is named.conf

[code:1]options {
directory "/etc";
pid-file "/var/run/named/named.pid";
allow-recursion { localnets; 127.0.0.1; };
};

zone "." {
type hint;
file "/etc/db.cache";
};

zone "domain1.com" {
type master;
file "/var/named/domain1.com.hosts";
allow-transfer {
127.0.0.1;
localnets;
};
};
zone "domain2.com.hk" {
type master;
file "/var/named/domain2.com.hk.hosts";
allow-transfer {
127.0.0.1;
localnets;
};
};
zone "domain3.com" {
type master;
file "/var/named/domain3.com.hosts";
allow-transfer {
127.0.0.1;
localnets;
};
};
zone "domain4.com" {
type master;
file "/var/named/domain4.com.hosts";
allow-transfer {
127.0.0.1;
localnets;
};
};
zone "domain5.com" {
type master;
file "/var/named/domain5.com.hosts";
allow-transfer {
127.0.0.1;
localnets;
};
};[/code:1]
