[jira] [Created] (LUCENE-8389) Could not limit Lucene's memory
consumption
changchun huang created LUCENE-8389:
---------------------------------------
Summary: Could not limit Lucene's memory consumption
Key: LUCENE-8389
URL: https://issues.apache.org/jira/browse/LUCENE-8389
Project: Lucene - Core
Issue Type: Bug
Components: core/index
Affects Versions: 3.3
Environment: |Java Version|1.8.0_102|
|Operating System|Linux 3.12.48-52.27-default|
|Application Server Container|Apache Tomcat/8.5.6|
|atabase JNDI address|mysql jdbc:mysql://mo-15e744225:3306/jira?useUnicode=true&characterEncoding=UTF8&sessionVariables=default_storage_engine=InnoDB|
|Database version|5.6.27|
|abase driver|MySQL Connector Java mysql-connector-java-5.1.34 ( Revision: jess.balint@oracle.com-20141014163213-wqbwpf1ok2kvo1om )|
|Version|7.6.1|
Reporter: changchun huang
We are running Jira 7.6.1 with Lucene 3.3 on SLES 12 SP1
We configured 16GB Jira heap on 64GB server
However, each time, when we run background re-index, the memory will be used out by Lucene and we could not only limit its memory consumption.
This definitely will cause overall performance issue on a system with heavy load.
We have around 500 concurrent users, 400K issues.
Could you please help to advice if there were workaround or fix for this?
Thanks.
BTW: I did check a lot and found a blog introducing the new behavior of Lucene 3.3

You should really try asking on an Atlassian support forum since Jira is
their project and they support it. This bug database is for tracking issues
about Lucene itself. Also please note that Lucene 3 is many years old now,
and no longer receiving bug fixes. The current version is 7, soon to be 8,
so even if there is a real issue with that version of Lucene, you are
unlikely to get much help with it now.
