-----------------------------------
Summary: ListenSyslog spin-loops CPU, spikes load to 150%
Key: NIFI-1208
URL: https://issues.apache.org/jira/browse/NIFI-1208
Project: Apache NiFi
Issue Type: Bug
Components: Extensions
Affects Versions: 0.4.0
Environment: Raspbian Jessie (Debian-based), Raspberry PI 2, 1GHz x
4cores, 1GB RAM, Oracle JDK 8 for ARM
Reporter: Andrew Grande
Priority: Critical
I've installed today's NiFI 0.4.0 snapshot on the latest Raspberry PI and
configured a syslog listener. After forwarding my RPI syslogs to this NiFi
listener, things seem to work ok (for now just sending to a remote cluster for
collection).
However, 'top' shows that the nifi process taxes CPU at around 150%, varying.
ListenSyslog stats show 1,500,000 tasks per a sliding 5min window.
