Cloudlinux Not Limiting I/O - Imap

[info]

Causing Server to Halt

[info]

I have a big account 80GB thats is causing a 100% I/O problem with 3 imap proceses. We had to disable the account.

The processes run like the user but are not being limited by Cloudlinux.

The Cloudlinux Kernel is the latest one:
Linux xxxx.com 2.6.32-458.18.1.lve1.2.39.el6.x86_64 #1 SMP Mon Sep 16 12:10:28 EEST 2013 x86_64 x86_64 x86_64 GNU/Linux

Cagefs is active for every account in the node.

The LVE for the user is not reporting any unusual but the thruth is other.

Let me know what else should i check or maybe is a bug in the System.

Carlos,

We don touch email processes at all.
If you want to limit IMAP processes, you will need to install experimental processes:

http://www.cloudlinux.com/blog/clnews/386.php

And run:

echo -n +/path/to/the/imap_process > /proc/lve/enter

To disable it:
echo -n -/path/to/the/imap_process > /proc/lve/enter

This is available only in the latest kernel, and this has to be executed on system start up.

Ah Thanks, that explains a lot.

Seems like we have to solve the problem the old way !

This is an active production server where im not very pleasant to execute an experimental feature like this.

We would wait for it to be mature enough.

Regards
