"No space left on device" caused by the size of my subreports?

[kburns]

This seems like a serious issue, so I figure it deserves it's own thread.

I have created a report with 3 sub-reports each separated with a page break. When I run it through jasper server, it takes a very long time to return. Eventually it gives the following error after completely filling up the machine with temp data and crashing the server. Because this effects our production server it is a very serious issue.

Oh my!
The server has encountered an error. Please excuse the inconvenience.

Previously I had this problem with a report containing 2 sub-reports separated by a single page break. The solution was in changing the size of the sub-reports in the main one by making them very large in width and very short in height.

Has anyone else come across this problem?

I fixed this problem by stacking my subreports and page breaks on top of each other in the main.jrxml leaving not a pixel of space between them.

[subreport 1]
[page break]
[subreport 2]
[page break]
[subreport 3]

Clearly this is a bug that needs to be dealt with, but more importantly we need better error messages. 

"net.sf.jasperreports.engine.JRRuntimeException: java.io.IOException: No space left on device"

^ makes no sense.
