        Hi guys,

        I have a loadbalanced BizTalk group with two BT servers and an external sql. I use the file adapter, pop3 adapter and msmq adapter for receiveing and sending files. The pop3- and msmq- adapters have a separate hostinstance which only runs on one leg. (no clustered hosts.)

        I use convoys, maps and some custom pipelines… but the xml messages I process is typically quite small.

        I’ve separated the system into Application-, Integration-, FileSend-, FileReceive-, Tracking-, MSMQ- and POP3- host.

        The problem is that the hostinstances performing the actual messageprocessing (Application, Integration), sometimes stumbles into an uncontrolled memory frenzy. This in turn results in message delivery/publishing throttling, and my “real time”  system crash and burn…

        The only solution, which of course isn’t a solution, is to restart the host instances…

        Does anyone have a suggestion to what might cause this, maybe a similar problem in the past?

        Thanks, Ole-Petter

           Hi,

          You can use throttling threshold to get rid of this issue.

          Host –> Advancd –> Throttling Threshold –>

          1. Change Process Momory usage to 80 ( default value is 25).

          2. Database Connection per CPU – 30 ( default is infinite (0))

          Thanks,

          Nandika

                  Thanks Nandika,

                  I’ve been trying to adjust the throttling threshold values, but I’m concerned about the total process memory use.

                  Is this a legitimate concern, or can I send this threshold “throug the roof” as you say.

                  The total memory threshold for the entire group will exceed the servers physical memory.
