Joseph Witt commented on NIFI-2669: ----------------------------------- full clean build w/contrib check all good. Code changes looks good and clearly addresses resource leak. Live testing at 100+MB/s went very well on default setup. Nice! > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
