Hello, we are running EO-PDF (latest - v21.3.18) from a .NET-Core 3.1 web application. We are deploying to App-Services. When we request a report we a generally generating two PDF's (one is a coversheet [which is one page] while the other is a report [which could be 1 page or could be say 100 pages]). Although the application handles this the first couple of times (each request taking around 15 seconds) we then constantly get timeouts on the report (in the case tested the report was only around 10 pages):-

System.Exception: Time out expired before the page can be loaded.

I have created an Azure memory dump and sent it to your private email address - with the timeouts I wondered whether further deadlocks might be occurring

Can you help ?

Hello, I've done some testing and so far the new build looks good - no timeouts

In terms of how I collect the memory dump, I basically followed these steps (outlines the standard way to get the dump from Azure-AppServices)

...so not sure what went wrong with the managed/unmanaged thread information
