When a report retrieves a huge amount of data, more than 10MB - default value of DataEngine.MEMORY_BUFFER_SIZE, files are created in the temporary system folder to cache the data while report generation is in progress. 

But once the report is generated, these files are not being deleted. They are only deleted when the ReportEngine is shutdown or in our case web-server shutdown/restart.

The DiskDataSetCacheObject class is creating the DataEngine folder to hold the DataSetCacheObject. Because of the complexity of the report, the data.data file created is huge. These files are present till the webserver is rebooted. We have a long running server and hence reboots aren't common and the system temporary folder doesn't get cleaned up. The /tmp space is getting filled up and over the last 6 months, all the space allocated has been used up creating problems on the server.

Is there a way to clean up the files once the report is generated? Or is this as designed? If it is as designed, then would need this to be taken up as an enhancement.


Reproducible: Always
