I am trying to put a limit to the memory used by an application pool within IIS 8.5. My problem is that if I put a limit that looks significantly greater than the typical memory usage, it is recycle once in a few minutes.
Context information comes below.
Initially, I have put a limit of 8GB from the UI and and my applicationhost.config looks like this:
<add name="AppPool" autoStart="true" managedRuntimeVersion="v4.0" startMode="AlwaysRunning">
<processModel idleTimeout="00:00:00" />
<recycling logEventOnRecycle="Time, Requests, Schedule, Memory, IsapiUnhealthy, OnDemand, ConfigChange, PrivateMemory">
<periodicRestart memory="8192000" time="00:00:00">
<schedule>
<clear />
<add value="01:00:00" />
</schedule>
</periodicRestart>
</recycling>
Reading this article, I realized that the value may be invalid, as it indicates a maximum value of 4,294,967 KB. So, I put this value (from the UI) and it is properly reflected in the configuration file.
If I remove the memory limit, w3wp process does not go beyond 2GB of used memory and the recycle does not happen.
The reason of the recycle (reached memory limit) is confirmed by reading Event Viewer (source = WAS).
Question: how can I configure the memory limit without the recycle issue?
