--------------------------------
Summary: HTTP-based Site-to-Site leaks threads/memory when unable
to communicate with remote instance
Key: NIFI-2669
URL: https://issues.apache.org/jira/browse/NIFI-2669
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Reporter: Mark Payne
Assignee: Mark Payne
Priority: Blocker
Fix For: 1.0.0
I am using HTTP-based site-to-site to communicate with a remote instance of
NiFi. I am seeing problems communicating, which is okay. But I am seeing CPU
load of 600-700 on my system with 32 cores. I am also seeing in a thread dump
10's to 100's threads with the name "I/O dispatcher" and am seeing OOME's. A
heap dump shows that the OOME is caused by 64K byte arrays, each being filled
with 0's. The byte[] is coming from class
org.apache.http.impl.nio.conn.PoolingNHttpClientConnectionManager.
