You'd better send complete buildable project to support@rocketdivision.com - it'd save a lot of time to all of us

Thanks!

I am sorry but i think i did not understand your reply.
Did you mean to say that i should use the "ReleaseDevice" method of Device object ?

No, ReleaseDevice is used after LockDevice. You don't need it.
I was speaking about FinalRelease (it's something like destructor for ATL-COM objects). It will be called by .NET garbage collection when the variable will be released.

1. Don't call thread.abort. Because in this case some objects will not free the memory.

2.

Code:

        Dim objDevice As New StarBurn.CDeviceClass
        objDevice = objDevices.GetDevice(0)

This two lines of code creates 2 objects. Of course both of them will be released, but only when th Garbage Collection will decide to do it.
Try to use the code like that:

Code:

        Dim objDevice 
        objDevice = objDevices.GetDevice(0)

The same problem in your loop:

Code:

        For intLoop = 0 To intTotal - 1
           Dim objDeviceInLoop 'As New StarBurn.CDevice
           objDeviceInLoop = objDevices.GetDevice(intLoop)
           CurrentDevice = objDevices.GetDevice(intLoop)
           Exit For
        Next       

And here:

Code:

        Dim objDiscInfo 'As New StarBurn.CDiscInfo
        objDiscInfo = CurrentDevice.GetDiscInfo()

Hello Anton,

I have mailed the sample project as you have said.
Everything in StarBurn OCX was working fine until i came across this Problem.
:cry:

I am anxiously waiting for your reply.

Regards,
Annie.

Hi,

I have verified memory usage. When we create Burner obejct to burn data - it allocates memory for a cache (160Mb).
Then If you adding folder or importing data from previous sessions, It allocates some memory for directory structure and filesystem representation structure.

So 230Mb is a too small limit of memory for burner.Can you increase this value?

ps. We are now checking possible memory leaks.

staff

Hello Alexey,

Thank you for your reply and know how about the memory usage of starburn. I think you have misunderstood the problem.

The problem is that when we burn jobs of more than 230 MB size (containing numerous files and folders) , the system hangs up due to high memory utilisation.

This surely indicates a memory leak somewhere in the OCX. Pls do have a look into it.

Annie

While guys are checking memory leaks (quite a lot of OCX users so far nobady reported nothing like this before...) I'd strongly recommend you to do what you've been pointed at - increase amount of available to ASP.NET memory. If it would work and after OCX would get freed whole memory would be freed as well - there's no memory leaks and it's just ASP.NET configuration problem.

We were not able to reproduce the problem here so far but in a day or two we'll have whole picture.

Hello There ,

Sorry for not reporting earlier , but i have been following this thread for quite some time now as we also are facing the same problem.

The application Shuts down when we try to write large amount of data. Have also tried increasing the memorylimit of machine.config to 80% , but does not help.

Pls advise.

Regards
Ashutosh

I am not hesitant to increase the memory allocated to ASP.NET in machine.config.

The reply posted by Alexey confused me as i was referring to my Project which was 230 MB in size, whereas Alexey was referring to 230 MB as the size allocated to ASP.NET worker process (which was not explained clearly).
It was Anton's reply and then Ashutosh's reply which pointed out as to what i was supposed to do.

Will do the change and let you know.

Regards,
Annie.

Yes, please try and let us know. That would help us to pin the problem. Thanks!
