            Bug ID: 241937
           Summary: syslogd truncates logged messages to 480 bytes
           Product: Base System
           Version: 11.3-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: standards
          Assignee: standards at FreeBSD.org
          Reporter: pi at FreeBSD.org

A change to bring syslogd into RFC5426 land *enforces* a max. length of 480
characters, while the RFC clearly states:

3.2.  Message Size

[...]
   IPv4 syslog receivers MUST be able to receive datagrams with message
   sizes up to and including 480 octets.  IPv6 syslog receivers MUST be
   able to receive datagrams with message sizes up to and including 1180
   octets.  All syslog receivers SHOULD be able to receive datagrams
   with message sizes of up to and including 2048 octets.  The ability
   to receive larger messages is encouraged.

So, please, issue a fix for this. The size the implementation must
minimaly support should not be the size the implementation can maximally
support.
