[Dovecot] Dovecot + OCFS2

[Jon Blazquez]

Thank you for your response,
With sendmail we have achieved to limit the load :

define(`confMAX_DAEMON_CHILDREN', `15')
define(`confCONNECTION_RATE_THROTTLE', `2')dnl
define(`confQUEUE_LA', `5')dnl
define(`confREFUSE_LA', `4')dnl


With this configuration the LOAD only reaches 20 ;-) but it’s not the 
solution.
The cluster is formed by 3 nodes. The load balancer sends mails to a 
node, when it's full (LOAD 4-5) it denies receiving more mails so the 
load balancer sends them to the following node in the cluster and so on...
In the first node the load continues increasing until it reaches roughly 
20, then it falls down.

This is a temporary solution but we don’t know where exactly the problem 
is: dovecot’s deliver, ocfs2….
Any help would be appreciated,

Jon
