Manuel Loayza created NIFI-7266: ----------------------------------- Summary: NIFI 1.4.0 gets unresponsive after heavy load Key: NIFI-7266 URL: https://issues.apache.org/jira/browse/NIFI-7266 Project: Apache NiFi Issue Type: Bug Components: Configuration Affects Versions: 1.4.0, 1.3.0, 1.2.0 Reporter: Manuel Loayza Attachments: Screen Shot 2020-03-17 at 3.18.27 PM.png
We have 2 clusters (6 instances each one) running with NIFI 1.1.2 + JDK 8u121 + Linux CentOS The traffic get divided between those 2 clusters: 1. TPS: 2700 - EAST cluster 2. TPS: 980. - WEST cluster We have tried to migrate to NIFI 1.2.0, 1.3.0, and 1.4.0, but the cluster with higher TPS (EAST) got stuck after 4 hours of intensive traffic. Also it web console got unresponsive. I've tried many things to fix this thing, but only thing I got was to increase the time from 4 to 6 hours before it fails Our current instances are running on AWS and each EC2 instances has 8 cpus (c5.2xlarge), and 16GB RAM. I've tried to use c5.4xlarge (it doubles the cpu and ram), but I got the same outcome. I don't have a clue to figure it out what the issue is. Also I have a datadog dashboard to track some java head metrics but everything looks normal. What should I do to find why those new better instances are failing? is it memory or disk space or threads got stuck? Why an old NIFI cluster conf works better than a new NIFI? Hope you can help me with this. Thanks -- This message was sent by Atlassian Jira (v8.3.4#803005)
