Load management/deadlock in instances

Hallo,

Is there a way to have webobjects send a message if there is to much traffic 
on an Application and a new instance is needed? WO cannot start new 
Instances for a given App by itself, when it needs them, is that right?

When an instance does no longer respond to requests but it is not "seen" as 
dead by WO - Is this usually due to a programming problem connected to the 
retrieval of Database Data? Could it also be caused by a memory problem of 
the Machine the App server runs on or of too little memory in the JVM?

If this happens, is there a way to have WO send the error to an email 
address? I know I can give an email to the app to send error messages there. 
Will this also apply to those errors like "no instance available" or "your 
request produced an error" which occure very early in the response circle?

Thanks for some input.

Regards,
Ute
