Hi,
We are working on this issue. We have seen this sporadically in our Azure test environment as well but we still do not have a way to reproduce it consistently. If you have any tips to reproduce it faster please share with us.
Thanks!

Thanks for the reply.
We also do not know how to reproduce it, it is happening randomly.
Is there an ETA for this issue as it's creating a problem for the users?

Unfortunately we do not have an ETA yet because we have not yet found out the root cause. As we working on the issue, we will reply here again as soon as we have any update.

Hi, We have tracked down this to low memory error and created a new build that can recover from low memory situation better. Please see your private message for the download link to the new build. However ultimately there is no way to completely avoid crashes caused by memory restrains. Since your system is an I2V2 system which has 16GB memory, it is unlikely that a single conversion would hit this limit. As such the issue most likely occurs when you have multiple concurrent conversions. So you may want to try to reduce this value: https://www.essentialobjects.com/doc/eo.pdf.htmltopdf.maxconcurrenttaskcount.htmlThis property serves as a "circuit breaker" that would fail the conversion right away if the number of concurrent conversion tasks reaches the limit. In this case a HtmlToPdfException would throw with its ErrorCode set to EngineBusy. You can detect this case in your code and act accordingly (for example, display a "server busy, please try again later" message). If you continue to experience crashes please try to capture runtime log and send the runtime logs to us. The code would be something like this:
Code: C#
try
{
HtmlToPdf.ConvertHtml(....);
}
catch
{
string log = EO.Base.Runtime.GetLogs();
//save log into a text file and send it to us
}
See here for more information on sending test file to us: https://www.essentialobjects.com/forum/test_project.aspxMake sure you update to the new build we send to you first. We will investigate further once we receive the logs. Thanks!

The file in the inbox is 2023.4.8.0,
Question is: is that a "newer" version?
Because the current public release version is 2023.4.26.0.
And while trying to install the 2023.4.8.0 on a dev box with 2023.4.26.0 already installed,
the setup will complain that a "newer" version is already installed.

The new build was sent to Shanto. Not to you. We have now sent the new build to you.

There have been various performance related issues, some were resolved in previous builds, some were not reproduced/confirmed, some were closed as non issue. If you can point to a specific forum post, we should be able to give you a more definitive answer about the outcome of that particular issue.
