+ <listitem><para>The maximum line length to permit when converting stream logs into record logs. When a systemd
+ unit's standard output/error are connected to the journal via a stream socket, the data read is split into
+ individual log records at newline (<literal>\n</literal>, ASCII 10) and NUL characters. If no such delimiter is
+ read for the specified number of bytes a hard log record boundary is artificially inserted, breaking up overly
+ long lines into multiple log records. Selecting overly large values increases the possible memory usage of the
+ Journal daemon for each stream client, as in the worst case the journal daemon needs to buffer the specified
+ number of bytes in memory before it can flush a new log record to disk. Also note that permitting overly large
+ line maximum line lengths affects compatibility with traditional log protocols as log records might not fit
+ anymore into a single <constant>AF_UNIX</constant> or <constant>AF_INET</constant> datagram. Takes a size in
+ bytes. If the value is suffixed with K, M, G or T, the specified size is parsed as Kilobytes, Megabytes,
+ Gigabytes, or Terabytes (with the base 1024), respectively. Defaults to 48K, which is relatively large but
+ still small enough so that log records likely fit into network datagrams along with extra room for
+ metadata. Note that values below 79 are not accepted and will be bumped to 79.</para></listitem>
