max number of binder threads

[Ubuntu guy]

Hi,

I have a senario where in mediaserver has 16 binder threads and all
of them waiting for a lock to be released. Does it mean all other
binder calls from other process to mediaserver wouldn't be serviced?
and if so, what would the state of that call be? Will a remote
exception be thrown or will the call wait forever?

It most likely means there is a deadlock in the media service.  There is a limit of 16 binder threads, but in practice this won't be a problem unless you have a bug where the threads are unable to return.  Incoming calls will block until a thread is available.

Hi, Dianne

I have another question on the binder threads in service process,
does every binder thread has different instance of mediaserver, or
they just share the same instance?
and how to guarantee the resource safe between thread?

Thank you.
