Java heap space while exporting

ReportServer ReportServer (EN)

Hello again!

I faced with inability to export files even average sizes. When report file grows up to 30mb, reportserver throw error 504 with timeout while exporting.
Tomcat writes in localhost log this:

If it’s metter, report is BIRT, but with other types of reports this error occurs sometimes.

Hi Glandike,

the problem is a too restricted memory setting for ReportServer. You’ll need to increase the amount of memory given to Tomcat.

Cheers,
Arno

When i had increased the memory on the server, next error has been revealed:

 Error: An error occured during report execution.
Report could not be loaded. It might be that ReportServer cannot access its temporary files (specified in rs.tempdir). If this error occurs repeatedly, please contact an administrator.
To get help please contact an administrator.

Moreover, the same question already [topic=113]exist[/topic] but it still without answer. Could you explain a bit about this error?

And sometimes it seems that the file has already been formed, but when it starts to load, loading immediately stops with “Network Error”.

I am afraid without additional information there is not much I can tell you. The error indicates that something went wrong when ReportServer tries to retrieve a generated report. As there a many factors that can cause this there is no “check this” solution. The best approach is to monitor the logs carefully when executing the report to see if anything there pops up. If it is a BIRT report you are running, you may also try executing it as HTML as this sometimes reveals additional information about a problem within the report.
