Hi,
I am running a cluster of five nodes and one of them just quit for no apparent
reason... at least I could not find anything wrong on the system.
Here is a section of the logs. You can clearly see that there is a 8 minutes
gap before I manually had to restart Nifi. I've looked in /var/log/messages
and Nifi's log files but could
not find any reason for this to happen...
any thoughts/ideas?
