Our Logstash has hung up(not terminated) on the 29.7. 13:55 so that no events where processed.
Curiosly on the 30.7. 14:10 it has started again but threw only Errors(see under config decription) until i restarted it on the 31.7. 7:30.
After the restart it again processed normally the backlogged events.
The logstash config is mostly the default with the following exceptions:
It was installed with yum on CentOS 7 in Version 5.4.3 (upgraded from 5.3.2 on the 17.07.2017).
The hang up occured without an error.
The error that was continuossly thrown(every 5 seconds) on the next day is an IOException (it will not let me post the complete error).
Knows someone what the cause for this error is?
