Crash in CEFLib after long run in windows.

[vivek67]

Hi,

We have a Windows & Mac application with CEF embedded within it. We have a mechanism where a widget (part of the page) refreshes every 1 minute.

While performing long run test, we consistently see a crash in Windows after the above said senario is run for about 40 hours.

We have enabled logging from CEF Library and below are the last few lines of the CEFLibrary logs.

Code: Select all

[0912/172903:INFO:CONSOLE(0)] "Application Cache Cached event", source: https://gs0.salesforce.com/one/one.app (0)
[0912/191405:ERROR:dns_config_service_win.cc(739)] DNS config watch failed.
[0914/074456:INFO:CONSOLE(0)] "Uncaught SyntaxError: Unexpected end of input", source: https://gs0.salesforce.com/one/one.app (0)
[0914/083759:FATAL:platform_canvas.cc(70)] SK_CRASH


I also have the Crash Dump (which is a binary file so can't upload in this post) I can share this to any mailid on request.

Can anyone please advice what might be the casuse of this consistent crash in windows during long run scenarios where a part of the page is being refreshed every one minute.

What CEF version and Windows version? Can you provide a symbolized stack trace for the crash? Debug symbols are available from http://cefbuilds.com.

We use version 3.1650.1562 of CEF.

1650 is a pretty old branch and the problem may already be fixed. Can you test with the 1916 or 2062 branch?
