ObjectDisposedException with Native Sockets #542

Closed ProbablePrime closed 5 months ago

ProbablePrime commented 5 months ago

Library version: 1.2.0

Framework: Mono

OS: Linux (Ubuntu)

I'm periodically seeing System.ObjectDisposedException on one of our servers:

Jan 28 06:17:32 skyfrostepyc mono[1766650]: System.ObjectDisposedException: Cannot access a disposed object.
Jan 28 06:17:32 skyfrostepyc mono[1766650]: Object name: 'System.Net.Sockets.Socket'.

It looks like the Available property of a socket can also throw ObjectDisposedException

Which is not caught in NativeReceiveLogic
