Could it be that the websites you requested tried to open a print dialog?

Also, do you use ajax handlers?

Print-Dialog, do u mean for a printing a page? No :D

Yes, to synchronise data between CEF and LUA.

Problem is still existent, but since 1.5.3 the crashes has been very increased.

Problem is caused by a CEF-Browser which is used for a smartphone and is running in the background.
In the background the only action that will be executed is AJAX-Handlers with jQuery, i sync the data every few seconds between LUA and JS.

Here are multiple crashdumps from 3 clients.

Problem is definitly caused by AJAX-Handlers.
After temporary removing AJAX-Functions we had no more crashes.

Used JS-Code: https://pastebin.com/BUwNiHKR [^]
Used LUA-Code: https://pastebin.com/DvskC5AL [^]

Crash is completely random, sometimes with error message sometimes without any message.
When changing the JS-Interval to 50ms it doesn't seems that the crash happens earlier.
