Shutdown crashes in v120 and above

[ssaraf]

Hi, we see a lot of shutdown crashes in v116, v120 & v121. The call stack is similar to

[ 00 ] logging::LogMessage::~LogMessage() ( logging.cc:937 )
[ 01 ] static void CefFrameImpl::OnDisconnect(CefFrameImpl::DisconnectReason) ( frame_impl.cc:609 )
[ 02 ] mojo::InterfaceEndpointClient::NotifyError(std::__Cr::optional<mojo::DisconnectReason> const &) ( interface_endpoint_client.cc:739 )
[ 03 ] static void base::internal::Invoker<base::internal::BindState<void (mojo::internal::MultiplexRouter::*)(bool),base::internal::UnretainedWrapper<mojo::internal::MultiplexRouter,base::unretained_traits::MayNotDangle,0>,bool>,void ()>::RunOnce(class base::internal::BindStateBase *) ( bind_internal.h:920 )
[ 04 ] static void base::internal::Invoker<base::internal::BindState<void (mojo::Connector::*)(const char *, unsigned int),base::internal::UnretainedWrapper<mojo::Connector,base::unretained_traits::MayNotDangle,0>,base::internal::UnretainedWrapper<const char,base::unretained_traits::MayNotDangle,0> >,void (unsigned int)>::Run(class base::internal::BindStateBase *, unsigned int) ( bind_internal.h:933 )
[ 05 ] void base::internal::Invoker<base::internal::BindState<void (*)(const base::RepeatingCallback<void (unsigned int)> &, unsigned int, const mojo::HandleSignalsState &),base::RepeatingCallback<void (unsigned int)> >,void (unsigned int, const mojo::HandleSignalsState &)>::Run(class base::internal::BindStateBase *, unsigned int, const struct mojo::HandleSignalsState & const) ( bind_internal.h:933 )
[ 06 ] static void mojo::SimpleWatcher::OnHandleReady(int, unsigned int, const struct mojo::HandleSignalsState & const) ( simple_watcher.cc:278 )


Do we have any workaround or solution for the same?

Try to run with --enable-logging and check what the (probable) LOG(ERROR) prints.
Most likely the frame OnDisconnect receives a reason different than DisconnectReason::BROWSER_FRAME_DETACHED is still navigating and attempts to call CefFrameImpl::ConnectBrowserFrame, but without a debug it's hard to tell.

I would try to call browser->StopLoad() for each browser still alive at the moment of shutdown.

I have noticed the disconnect crash some time ago. My solution was to change from FATAL to ERROR as suggested as one of the possible solutions (but that inside of chromium src). Did not saw the crash since.
