after managing to update to Graylog 3.0 (because the UI was bugging me to update), I noticed that all our newer servers do not send syslog messages to Graylog anymore. The only servers for which logs still come in are the old ones (we are talking wheezy here). The error thrown by rsyslogd is
3661.491220099:main Q:Reg/w0 : Called LogMsg, msg: unexpected GnuTLS error -28 in nsd_gtls.c:1755: Resource temporarily unavailable, try again. rsyslogd: unexpected GnuTLS error -28 in nsd_gtls.c:1755: Resource temporarily unavailable, try again. [v8.24.0 try http://www.rsyslog.com/e/2078 ]
gnutls-cli works fine and connects. Does someone have a clue to why this is? I have been trying for a few hours to figure out what the problem is but I can’t put my finger on it.
GELF still seems to work fine.
