AOS doesn't accept new clients

[gb]

Hi,

and I am sorry for English. I don't have Russian keyboard.

Axapta 3 + SP2.
Problem:
Axapta cluster with 4-5 AOS servers, number of users 300.
Every day at least one AOS server stops accepting a request from new client. Because of the cluster nobody can login.
The only way to fix it is to take that AOS out of the cluster.
It is very painfull as this is 24X7 environment.

I would appreciate any comments and can provide any additional inforamtion.

Thank you,
gb
