Hi,
My graylog install has been working well for months. Today I noticed the last message in the ‘all messages’ stream is from 5am today. It’s around 12:30pm right now.
I have syslog:514 listening on this box and graylog Local inputs
is fed from this port. The System > Inputs status shows 31Msgs/s for last 1 minute average.
I rebooted the Graylog box within the past hour and a Java process seems to be running quite high. I’m not a Graylog expert by any means. Any thoughts where to look for the problem?

The last 10 messages from graylog-server log are below. Nothing much to go on there:
