Hello, we are running EO-PDF (v22.0.68) 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 "Child process exited unexpectedly" as follows:-

Child process exited unexpectedly.

I have created an Azure memory dump as well as captured the Internal log file and sent links to your private email address

Can you help ?

We have sent another new build (22.1.1) to you last week. Have you got a chance to try that build yet?

Hello, we're still testing. Although the version you sent through seems to be more stable than the prior we are still getting some unexpected timeouts and "Failed to start image manager." on small reports. We have Azure AppServices SelfHeal on so it eventually recovers however not sure why it is happening. I have seen for the "Failed to start image manager." issue you recommend implementing the EO.Base.Runtime.Exception event to get further information which we will look to do over the coming days
