Plesk problem

Memory and Qmail queue

I´d like to know if exists any way to accelerate or flush the Qmail queue?

I migrate 150 clients to Plesk 9.2.3 CentOS 5.4, in a PowerEdge 2 Xeon processors and 8 GB of memory server machine, but today I saw that a top command that the memory usage was 7.9 GB. Is it normal the Plesk use a lot of memory?

Regards.

Hello,

Usually Qmail queue is growing due to too many messages in remote queue, because sending mail to remote servers takes much more time than delivering the message to the local mailbox.

By default Qmail uses up to 20 'qmail-remote' processes to deliver mail to remote servers. This value can be not enough if the server has heavy mail traffic. In this case you can increase number of simultaneously running 'qmail-remote' processes by creating /var/qmail/control/concurrencyremote file with needed value, for example:

# echo 50 > /var/qmail/control/concurrencyremote

Then restart Qmail. Please, see the following articles for more information:

To rebuilt qmail queue please, check the following article:

Thank you Nataliya. I will see this articles to solve me problem.

Other question:

I migrate 150 clients to Plesk 9.2.3 on CentOS 5.4, with a server PowerEdge 2 Xeon processors and 8 GB of memory server machine, but today I saw with a top command that the memory usage was 7.9 GB. Is it normal the Plesk use a lot of memory?

I have 500 clients to migrate for this server, but I don´t know if this server will bear the load, because a lot of memory used. The server has 8 GB of memory and is using all memory. In Plesk says it has 6 GB free, but the Linux command line tells me that only has 500 M.

Do I need to increase the memory of the server or is there another way to optimize the use of memory on the plesk?

What do you think?

Please, help me.

It is very difficult to say how much memory, CPU, other hardware resources consuming will be on particular Plesk installation because there are can be domains with hardloaded applications like Tomcat, Java, ColdFusion, with a lot of databases, subdomains, etc.
You can look at old Recommended Hardware Configuration for Plesk as example here - http://www.parallels.com/products/plesk7win/reqs/ But I'm not sure that it is actual now.
