      Description

      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
