I am trying to set sessionmark and watermark values in the adm_ServiceClass
table. I am using Biztalk 2004.

I have the following scenario I am putting the files in a designated input
folder using LoadGen tool @ 10 files per second. I want biztalk to pick thes
e
files up, process the files and output the files to the out folder. I have
one box each for receive, send, Orchestration and MessageBoxDB.

I have the following problem
-> Initially biztalk picks up files continuously and
orchestration host processes them (This is the behavior I want).
-> Suddenly the receive host stops picking up files and there is
no processing happening in the orchestration host or send host (I thought
receive  stops only under high load).
-> Then suddenly the processing starts and there is 100% CPU
consumption on Orchestration host.

I have tried setting lots of combinations for sessionmark and watermark, but
I am facing the above mentioned problem.

My questions is why does receive stop even if there is no load on
Orchestration, receive, send host or MessageBozDB?
What is the best way to determine values for sessionmark and watermark?

Thanks in advance.
