.. zeek:id:: smb2_discarded_messages_state
   :source-code: base/protocols/smb/smb2-main.zeek 350 366

   :Type: :zeek:type:`event` (c: :zeek:type:`connection`, state: :zeek:type:`string`)

   Generated for :abbr:`SMB (Server Message Block)`/:abbr:`CIFS (Common Internet File System)`
   version 2 connections for which pending read, ioctl or tree requests exceeds
   the :zeek:see:`SMB::max_pending_messages` setting. This event indicates either
   traffic loss, traffic load-balancing issues, or failures to parse or match
   SMB responses with SMB requests. When this event is raised, internal per-connection
   parser state has been reset.


   :param c: The affected connection.


   :param state: String describing what kind of state was affected.
          One of read, ioctl or tree.

   version 2 messages.

   See `Wikipedia <https://en.wikipedia.org/wiki/Server_Message_Block>`__ for more information about the
   :abbr:`SMB (Server Message Block)`/:abbr:`CIFS (Common Internet File System)` protocol. Zeek's
   :abbr:`SMB (Server Message Block)`/:abbr:`CIFS (Common Internet File System)` analyzer parses
   both :abbr:`SMB (Server Message Block)`-over-:abbr:`NetBIOS (Network Basic Input/Output System)` on
   ports 138/139 and :abbr:`SMB (Server Message Block)`-over-TCP on port 445.


   :param c: The connection.


   :param hdr: The parsed header of the :abbr:`SMB (Server Message Block)` version 2 message.


   :param is_orig: True if the message came from the originator side.
