Cloudlinux Not Limiting I/O - Imap

Causing Server to Halt
Rate this post:
I have a big account 80GB that's 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.
We don\'t touch email processes at all.
If you want to limit IMAP processes, you will need to install experimental processes:
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 i\'m not very pleasant to execute an experimental feature like this.
We would wait for it to be mature enough.
