Major issue with AR 2.0 for .net 2.0 - OutOfMemory Exception
Attachment: CrashDetail.txt

Hi,
we are using AR 2.0 for .NET 2.0 (4.1.0.1127). Here is some technical specs:
- Windows 2003
- IIS 6.0
- Net FrameWork 2.0 Beta 2
- C#
- ASP.NET
We are experiencing crashes on our server. (System.OutOfMemoryException).
The attached file contains the stack trace of 2 major craches. When this occurs, the server stops responding to Web requests. In most cases, we must stop IIS and in other cases we have to reboot the server.
Are you aware of such problems?

Hi,
we followed one of your recommendations: we are using the " CacheToDisk" property. This works great (the server is no longer crashing when creating or exporting a report).
We are still monitoring our server. Maybe we can blame the .NET 2.0 Beta 2 on this one, but we are having many memory problems!
We are still concerned by the fact that when we export a report to PDF, the server is using 5 Mb of RAM each time (for a rather simple report with 4 sub-reports (each report only displays 1 record) and it adds up every time the report is created. (Perhaps the Garbage Collector is lazy on that one.).
I will keep you inform on any positive or negative development.
Thanks for the great customer service!
Michel Loubier

1127 is not intended for use in the .NET framework 2.0 environment. See the following announcement:
http://www.datadynamics.com/ShowPost.aspx?PostID=75732
Also, be sure that if you are running multiple reports in the same application that you are calling Document.Dispose, report.Dispose, and setting the report to null.

We have made some changes in our code, but the problem is still present.
We now appropriately call the Dispose method of the PDFExport, Document and Report objects. (We even set the objects to "null"... just in case it does something good for us!).
The class in which we call the report's Run method implements the IDisposable interface. (We have added this implementation just to force the garbage collector to do its job ;-) ).
The problem remains: Each report creation takes 5Mb in memory... which after several hours (~ 5 hours) crashes the ASP.NET process and the server hangs.
I have found an article about a possible memory leak and SP1 (http://www.datadynamics.com/ShowPost.aspx?PostID=78584).
Is it possible those are related bugs?
Is there any time frame for the SP2 release or the next .NET 2.0 beta / release?
Thanks.

At the present, our project manager has stopped us from putting efforts into this problem. (Our Web Site is now running on a production server... we had to put it on-line.)
He configured IIS so the Application pool is recycled every 12 hours, thus freeing the memory.
In November, we will migrate our development computers and servers to VS2005 RC or release version and will upgrade to the latest SP available from you guys.
At that moment, we will verify if the problem still exists. (In my spare times, I'll try to create a simple project to recreate our bug).
I'll keep you inform of any development.
Thanks.

so got the new beta release working and i made a simple webapp with a 1 page report. i then ran microsoft ACT against the webapp and my memory was quickly running low...i then noticed in my task manager that "inetinfo.exe" was growing in size that would account for the loss in memory. also in the test results of ACT it showed http errors were occurring, which i think relates directly to inetinfo growing in size. any ideas as to why these http errors are occuring?

My app consists of the webviewer set to pdf output(I don't get any errors with html output). The crucial part of the test is that it should have more than 1 simultaneous user, I've found that above 3 users is when the http errors start to occur.

Hi,
We are using AR for .net 2.0 with .net framework 1.1. You said you are CachetoDisk property to prevent the web server from caching. We also face the same problem.
I wanted to know when the cached report gets deleted from the web server. Should we forcibly delete the cache by calling a method or whether it gets deleted when the report object is disposed?
Can any one help on this.
Thanks
Anguselvi

Hi there,
We are seeing a similar behaviour with PDFEXPORT in ActiveReports for .NET 1.0 (SP4),
we will be testing with a build which has CacheToDisk=true on the Document object,
The memory still seems to be climbing on the aspnet\w3p worker process on my dev machine.
Are there any other suggestions.
Thanks,
Rakesh Ajwani
