We are getting error System.AccessViolationException.

It seems to be an issue with concurrent users running our reports at the same time, but normally they run perfectly.
Our reports are returned as pdf's via the ResponseAsPdf method.

Any help would be appreciated.

Thanks,

We also return the reports normally (not as pdf's) for non-mobile devices and are having the same issue.

Hello,

Can you please check the last build and let us know about the result.
If the issue still present, please provide a more information about the issue.

Thank you.

We are running .Net 4.5.1.
System.AccessViolationException cannot be caught so it crashes our app pool causing everyone to lose their session.
Crashes on Stimulsoft.Report.Web.StiReportResponse.ResponseAsPdf and viewer.Report =.
I don't think the report matters in this issue just the timing.

I will test the latest build and let you know the results.

Hello,

Ok.
We will wait.

Thank you.

2016.1.8 appears to have fixed the issue!

I have not been able to get it to fail during testing.

Thanks for your help!!

I was able to get this error again when testing, so far just when using Stimulsoft.Report.Web.StiReportResponse.ResponseAsPdf.

Here is how I get the error in debug mode:
I log into Firefox & log into chrome.
I then run a 24 page report in Firefox and try to run the same report in Chrome as fast as I can click.
It usually takes a half dozen tries or more before I get the System.AccessViolationException error.

Any assistance would be appreciated.

Thanks,
Tony

Hello,

We have tested the WebViewer with a report which contains more than 50 pages(MS SQL data) and found no errors when viewing or when exporting using ResponseAsPdf method. We have updated the test page in the 3 major browsers - IE 11, Firefox, Chrome.
Please send us a test project and report with test data. Also, please try to reproduce the error on one of our test reports in your project.

Thank you.
