As i understand it, the kolab deamon does some maintenance work on the
mailboxes, creation of mailboxes/users, deletion and so on.
I see se same problem with kolabd, but in my case the installation is
damaged because i deleted the main domain on that server. So i have to
restart from scratch again.
If i start top i see kolab and ns-slapd consuming a lot of cpu.
What processes are active in your case?
