Environment
Jira Data Center on any version below 9.5.0
Cause
Jira creates a temporary directory to store many types of temporary files that should not be deleted while Jira is running as that could cause issues. As explained in the bug JRASERVER-46006: Jira doesn't clean up $JIRA_INSTALL/temp, Jira does not automatically purge this folder on versions lower than 9.5.0. As a result, the size of the temporary folder will increase over time, unless it is manually purged, and the health check error will eventually be thrown as soon as the Jira server starts running low on disk space.
Solution
Resolution 1 - Long term solution
In Jira 9.5.0, we introduced the Jira Temporary Directory Cleaner to solve the issue of instances running out of space. With the help of the feature, during startup, Jira will automatically clean its temporary directory defined by the java.io.tmpdir property. Please refer to Jira Temporary Directory Cleanerfor steps to enable the feature.
If you are running on any Jira version lower than 9.5.0, we recommend upgrading Jira to this version (or any higher version).
Resolution 2 - Short term solution
If you are unable to upgrade Jira, you may remove the files manually by following the below steps:
Login to the Jira server
Stop Jira
Manually delete the files under $JIRA_INSTALL/temp
Start Jira
It is safe to manually delete the contents of the JIRA INSTALL/temp directory, as long as Jira is not running. Jira uses this directory to store all sorts of temporary files (downloading add-ons, add-ons manually uploaded by users, CSV imports, etc), so deleting it while Jira is running could cause instability, data loss, and system crash.
