Folks,



The GZipStream class in .NET is throwing an exception during an OS
unseal/power up (first boot experience). The .NET system is fully up as
other apps seem to run fine.



Our code works fine when testing it on a PC that is already up.



After googling we found some people having similar issues when using
SQLServer ... but we are not using it.



Has anyone seen this?

.........





I think we could use some advice/analysis from Microsoft on this stack
trace, which is showing an exception from the GZipStream implementation. I
have Googled this and only found issues with people apparently misusing
SQLServer, nothing relating to compression/decompression. This occurs
occasionally during an OS unseal/power up:



......................Module: System.Runtime.Remoting.Proxies.RealProxy



Exception 1: System.IndexOutOfRangeException

Message: Index was outside the bounds of the array.

Source: System

Site: Void CreateTable()

*** Stack Trace ***



Server stack trace:

at System.IO.Compression.HuffmanTree.CreateTable()

at System.IO.Compression.HuffmanTree..ctor(Byte[] codeLengths)

Int32 count)

at System.IO.Compression.GZipStream.Read(Byte[] array, Int32 offset,

You'll have to be more specific. What is the GZipStream instance attempting
to do? When exactly does the application start? What is the exception?

See the exception at the end of the thread.

"Index was outside the bounds of the array" ...

It is doing a simple unzip of a compressed file/data.

It works fine when running on a PC ... it is failing during the "unseal"
phase of the first boot experience (when a customer gets their new PC and
turns it on the first time ... we run a few things).

I'm assuming this is more of a system question than a .NET question but
wanted to try here anyways.

Are you sure it can access that file? Might there be an issue with
permissions not having yet been set during the "unseal" phase?

You could try SharpZipLib instead

Thanks for the ideas Andrew. We'll check on the permissions.

Here is a bit more details in case it triggers something for the group.


What is the GZipStream instance attempting to do?

What is the exception?"

It should be sufficient for Microsoft to see that we are simply calling
System.IO.Compression.GZipStream.Read().
