ASP.NET sequentially executes requests that have the same SessionID, which means you may see the requests piling up in the queue if there are lots of concurrent requests that have the same SessionID. After you apply this fix, you can limit the number of the requests in the queue through the following AppSetting:
<appSettings> <add key="aspnet:RequestQueueLimitPerSession" value="50"/></appSettings>
If you marshal an array of struct A and an array of struct B as SAFEARRAY, and struct A and struct B have identical GUIDs, a memory leak may occur.
Note This update also contains cumulative updates that were released previously starting from October 11, 2016.
