rooling replication and many pop3d

[Oberdan Albertoni]

Hi,
I enabled replication between two servers with version 2.4.10 cyrus.
I set the option for the rolling replication, and it works fine but 
obviously I have a high CPU load.
Unfortunately after 10 minutes of running processes pop3d increasing 
from 50 to over 200, making the server unusable for customers.
Can you tell me why this increase is abnormal?
Greetings oberdan Albertoni.
