Question

cancel_message will probably lead to memory leaks

Opened this issue 5 years ago · 1 comments

Example situation:

Process A send a TcpOpen request.
Process B handles the message, allocates the TCP connection, returns the id.
Process A in the meanwhile cancels the TcpOpen.
Since process B isn't notified of the cancellation, we just leak the TCP connection.

I wish I knew more about distributed systems or actor models here, but I don't think there's a generic solution to that problem. The TCP interface should be changed to allocate IDs on the sending side.
