Jira is logging multiple cache flushes in the application logs
Platform notice: Server and Data Center only. This article only applies to Atlassian products on the server and data center platforms.
The following INFO messages can be seen in the atlassian-jira.log regarding specific caches being flushed. Example:
2021-11-04 15:08:41,001-0300 http-nio-8080-exec-18 INFO [c.a.c.e.c.a.j.i.f.l.column.DefaultColumnLayoutManager.filterColumnLayoutCache] Cache com.atlassian.jira.issue.fields.layout.column.DefaultColumnLayoutManager.filterColumnLayoutCache was flushed 2021-11-04 15:08:41,001-0300 http-nio-8080-exec-18 INFO [c.a.c.e.c.a.j.i.f.screen.CachingFieldScreenStore.allScreensCache] Cache com.atlassian.jira.issue.fields.screen.CachingFieldScreenStore.allScreensCache was flushed 2021-11-04 15:08:41,001-0300 http-nio-8080-exec-18 INFO [c.a.c.e.c.a.j.i.f.screen.CachingFieldScreenStore.fieldScreenCache] Cache com.atlassian.jira.issue.fields.screen.CachingFieldScreenStore.fieldScreenCache was flushed
Jira 8.19.0 and later
This is expected behavior and will not cause any problems or concerns.
This is useful when troubleshooting issues with Jira and to determine what caused a specific cache to be flushed. During the Jira startup you will see lots of these messages as it's expected behavior that several Jira caches are populated and flushed for the first time.
How to disable this feature
To disable logging on cache flushes, please follow these steps:
- Open the log4j.properties file (located in the Jira application installation directory).
Change the line below from INFO to OFF. Example:
log4j.logger.com.atlassian.cache.event = OFF, filelog
- Save the file and restart the node for the changes to take effect.
