SYMPTOMS
You may not be able to send or receive instant messages because the instant messaging server has stopped responding.



CAUSE
This problem may occur if the instant messaging server is being accessed by client programs that are outside the domain where the instant messaging server resides. If the instant messaging server cannot lookup certain attributes for that specific client program, the instant messaging router's DSAccess component does not cache any of the client programs attribute information. Because of this, the attribute information is retrieved from the client program every time an instant message is sent. This increases the time that it takes to send each instant message. If messages are being sent faster than they can be cleared from the queue, the messaging queue can grow to be very large. If the messaging queue grows too large, the server stops responding, and you cannot send or receive instant messages.
