Page Pool Errors

[Nate Braxton]

We have had page pool errors that have resulted in shutting down our
ports, thus taking all our personalized websites down with it.
Restarting services solved the problem temporarily.

Has anyone had problems similar to this or know what in XMPie might
cause these problems.

We have a Director, MI-2 Extension Server, and SQL Server with
Personal Effect 4.5.2.

Never experienced "page pool errors" exactly as you are describing
them.

With uProduce 4.6.2. with busy ICP-based campaigns, I experienced
"deadlock detected" on \aspnet_isapi.dll.

I managed to fix them, by:
* defining a separate application pool for each virtual folder,
assigned to each campaign;
* making the following changes in the .Net Framework machine.config:

Nate,

Do you have a stack trace? Alternatively, are you just assuming its an issue with IIS application pools? You could turn up the process reaping if thats a particular issue...

<microsoft_rant>
I personally hate the design and implementation of IIS because it makes hard to debug situations all too common... its not a patch on NGINX and the ilk.
</microsoft_rant>

Cheers, Tim
