EO v15.2.41.0

All threads seem to be waiting for more than 2 days, EvalScript call normally finishes within one minute. Are the following stack traces represent normal operation of EO WebView?

Some of the EO threads are waiting for closed EO handles.

I have found found MSDN reference for this: "If one of these handles is closed while the wait is still pending, the function's behavior is undefined." https://msdn.microsoft.com/en-us/library/windows/desktop/ms687025(v=vs.85).aspx

Hi,

This appears to be a deadlock somewhere in the browser engine (the native side). We have just post a new build that added remote debug support that may help to pin point this problem. Please update to the new build and then try to reproduce it again. Once the problem is reproduced, you can follow the steps outlined here:

http://www.essentialobjects.com/doc/common/remote_debug.aspx

Hopefully this will give us enough information to find out the root cause of this problem.

Thanks!

Hi,

We did find a problem that can cause this. We have posted a new build and emailed you the download location. Please try with the new build and see if the problem still occurs.

Thanks!
