Hi,
I've tried to reload QWebEngineView after renderProcessTerminated. I'm
deleting QWebEngineView and creating a new one. To crash render process I
just kill QtWebEngineProcess.
I'm able to create a new QWebEngineView just ok, but having problems with
sqlite somewhere in QtWebEngine code, possibly in QuotaDatabase.
Backtrace dumped to stderr after crash shows something strange, but VS2013
callstack shows calls from QuotaDatabase.
Backtrace:
[0314/164228:FATAL:connection.cc(1291)] database is locked
Backtrace:

Is there some kind of a clean way to reinitialize QtWebEngine in Qt
application short of full apllication restart?
If not, then maybe someone can point me to a way to fix this error with
locked database?
