Problem with cache and large reports

Kenneth Jonsson · Post by **Kenneth Jonsson** » Thu Oct 11, 2007 2:12 am

Hi y'all,

My report may have several thousand pages with text and images, so I enabled the cache function to reduce memory consumption.

This is a few lines of code to show what I did:

Stimulsoft.Report.StiOptions.Export.Pdf.ReduceFontFileSize = true;
ReportCacheMode = StiReportCacheMode.On;
StiOptions.Engine.ReportCache.LimitForStartUsingCache = 100;
StiOptions.Engine.ReportCache.CachePath = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
RegData(mDataSet);
Compile();
Dictionary.ImportXMLSchema(mDs);
Dictionary.Synchronize();
Render(false);

When some 150 pages are rendered, this error is thrown:
The process cannot access the file 'C:\Documents and Settings\kejo\My Documents\StimulsoftReportsCache\3c65008ea754432eb72edb9f18eb2ca5\be9e213ee12c46b1bdf031b230e0eef3.mch' because it is being used by another process.

Can I do anything to avoid the problem?

We use version 2007.3.0.0 from the patch SR_2007.09.24_R2005.zip.

Regards,
Kenneth Jonsson

All your steps are correct.

Maybe try to reduce LimitForStartUsingCache parameter to 40.

Could you please provide us with the test application or report template which produces such a result.

Thank you.

I send you the XML-file loaded to the report, and the report definition. But since rendering fails I can't send a proper dump of the report with all displayed images. Image files are the bulk of the report. Please look for a mail to support@stimulsoft.com with same subject as of this thead.

Thank you for the sample application and describing your requirements in detail.

The same issue is described here:

So the only way to avoid this behavior is to reduce size of the images. I've tested your report and code as well and for the smaller images I haven't met the exception.

Thank you.
