Hi,

The reason was very simple. Each barcode is represented as a picture. It consumes some resources. And asp process just was out of the required size of the memory.

Thank you.

Hello,

This is not depend from report engine. It depend from size and count of barcode components. For example if your report have 300 pages, on each page you have 10 barcode and image of one barcode have size around 1 mb, then you need 300x10x1.000.000 = 3 gb of memory. Also you need take in attention that asp.net process usually can take only around 500 mb. It depend from system settings. What you can do with this problem?[/quote]

1. Try to change ImageFormat property of StiWebViewer to Jpeg;
2. Do not render 300 pages on one iteration. Create 6 reports per 50 pages;
3. Do not use StiWebViewer. Output report results directly to pdf with help of following code: StiReportResponse.ResponseAsPdf(this, report);

Also please provide full error stack for this problem.

The size of my memeory is 2GB.Are you sure your report have not Memory Leak?

This is not possible for one report. This critical for 1000 reports. In this case you need use some special methodic to avoid compilation process.

Thank you.
