Doesnt work under high load

Being Fixed
We have implemented the latest version on 64bit and the document viewer crashes every 10 mins, we rolled back to 6.5.0 which looked more stable but that also crashes hourly. Only seems to happen when running 64bit, but moving to 32bit compatibility defeats the object of using 64bit! 

Faulting application name: w3wp.exe
Faulting module name: PortableEngine.Native.dll, version:
Exception code: 0xc0000005

Hi Robert,
We have a couple of similar reports but it's hard to replicate. For example, our live demo server does not have an issue. Do you think it's because of high load or because of specific document files? The problem is it's hard to catch exceptions from native DLL, unlike managed DLLs it crashes down the owner process when it faults.

I suspect the fault mostly occurs when converting specific documents to XPZ format in second step. Converting to PDF in first step is usually stable. We are currently working on new viewer which will not need XPZ format and will display PDF format directly. I think this will solve most of the weird native crashes. Later, we will also try to ditch native DLL and go full managed. The new version is very close to completion, I will let you know soon.
