Hello, we are running EO-PDF (latest - v22.0.40) 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 and sent it to your private email address
Can you help ?

Hi, We recently fixed a handle/memory leak in our HTML to PDF converter that might be the root cause of this problem. We will have a new build either this week or early next week with this issue fixed. So you can try the new build and see if that resolves the issue for you. If the problem continues with the new build, please try to capture debug log when the failure occurs and send the log to us. You would capture it like this:
Code: C#
try
{
HtmlToPdf.ConvertHtml(...);
}
catch
{
string log = EO.Base.Runtime.GetLogs();
//send the log to us
}
Once we have that log we will see what we can find. Thanks!

Hello, thanks for the reply - we currently have the latest version available (v22.0.40) installed - this is the version we have the posted issue against
I have added the (try/catch) code you have suggested in your reply and will send you logs when we next get the failure
Kind regards
Phil

Hi,
Build 22.0.40 is the one that has the leak issue and we will have a new build today (build 22.0.68) with the fix. So please try that build first once it's out.
Thanks!

Many thanks for the turn-around
