Hello, we are running EO-PDF (v22.1.13) from a .NET-Core 3.1 web application. We are deploying to App-Services. When we request a report, initially the requests are OK, however eventually we seem to get a "Timeout" (even on small [~5 page] reports) as follows:-
Conversion failed. Time out expired before the page can be loaded.
InnerException:
System.Exception: Time out expired before the page can be loaded.

Our settings are as follows:-
EnableEOWP=true
MaxConcurrentTaskCount=16
Note that we are also getting "Failed to start image manager" - it's difficult to know which one comes first (i.e. the Failed to start image... or the timeout) and hence identifying what is the root cause - if the root cause of the timeout issue is found (eg. locking with a parallel thread/process), this may determine what the real problem is
I have created an Azure memory dump and collected an internal log (using EO.Base.Runtime.GetLogs()) and sent the link to your private email address
Can you help ?
