I don't get web+ to crash with zooming in/out of google maps, but see what's described in #12497.

Indeed, this is once again a case where too many ports are created. My guess is it's because a lot of tiles are created for the map rendering. It can lead to just Web+ terminating or the app_server freezing, depending on who allocates a port first after the maximum number has been reached.

This is still a problem on latest HaikuWebKit 1.5.4.

KERN: 1305: DEBUGGER: Could not create BWindow's receive port, used for interacting with the app_server! KERN: _user_debugger(): Failed to install debugger. Message is: `Could not create BWindow's receive port, used for interacting with the app_server!' KERN: thread_hit_debug_event(): Failed to create debug port: No more ports available

Still running out of ports on that page. Assigning to Jua as he may know better than me about the rendering code in WebKit. Maybe we could detect this and crash the app before it freezes the whole system, too.

Pardon my utter ignorance but why would each tile need a port?

comment:11 by jua, 3 years ago

Haven't looked into it yet, but it probably creates lots of BBitmaps and accompanying BViews attached to them, which on the app_server side behave like offscreen windows (with their own threads etc). When I find time I will look why it creates so many and how to avoid it...
