184.108.40.206 SMB_COM_PROCESS_EXIT (0x11)
This is an original Core Protocol command. This command is obsolescent. It was declared obsolete in the LAN Manager 1.0 dialect (see [SMB-LM1X]) but continues to be included in later documentation. [CIFS] lists this command as obsolescent, and that designation is retained here.
An SMB_COM_PROCESS_EXIT request is sent by the client to indicate the catastrophic failure of a client process. Upon receiving an SMB_COM_PROCESS_EXIT request, the server MUST close any resources owned by the Process ID (PID) listed in the request header.
