This morning I was seeing bunches of errors in the server.log. I think I
tracked them to a syslog/tcp input. My rsyslog entry on the client is as
follows.
# Graylog
$template GRAYLOGRFC5424,"<%PRI%>%PROTOCOL-VERSION%
%TIMESTAMP:::date-rfc3339% %HOSTNAME% %APP-NAME% %PROCID% %MSGID%

*.* @@xxx.xxx.xxx.xxx:12204;GRAYLOGRFC5424
It seems the cause was memory errors on a compute node. The question is if
this is a graylog bug or expected behavior. There were a series of these
"com.fasterxml.jackson.core.JsonParseException: Unrecognized token 'xxx':
was expecting ('true', 'false' or 'null') at [Source:" errors. I'm running
the current versions of graylog-server and elasticsearch. The token 'xxx'
is a random character(s) and then a massive bunch of garbage characters
will follow the error.
