Package.Execute() Method Error

Hi,

I have a strange problem with calling packages from c# code. Packages start to execute, but never finish. Instead an error occures in eventlog:

(message is translated into english so it can sound a bit different)


Erring application AppName.exe, version 1.0.0.0, timestamp 0x4784c811, erring module ntdll.dll, version 6.0.6000.16386, timestamp 0x4549d372, exception code 0xc0000374, error shift 0x00000000000c87b7, process ID 0x1284, application start time 0x01c852ceb26bbad3.

In debuger, execution stoppes on line "DTSExecResult res = dtsPkg.Execute();", but no error is showed.

This behaviour occured unexpectally. Application worked correctly and in a minute I wasn´t able to execute any package from an application. I also tryed it from another computer and got the same error. Calling packages directly from management studio works fine.

OS:
Windows Vista Bussiness 64b

Code:

Package dtsPkg = new Package();

Variables variables = dtsPkg.Variables;

Microsoft.SqlServer.Dts.Runtime.Application dtsApp = new Microsoft.SqlServer.Dts.Runtime.Application();

dtsPkg = dtsApp.LoadFromSqlServer(@"\PackageName", "server", null, null, null);

dtsPkg.InteractiveMode = true;

dtsPkg.DebugMode = true;

dtsPkg.LoggingMode = DTSLoggingMode.Enabled;


dtsPkg.VariableDispenser.LockOneForWrite("FilePath", ref variables);

Variable pathVar = variables[0];

pathVar.Value = filePath;

variables.Unlock();

DTSExecResult res = dtsPkg.Execute();



I will be grateful for any ideas
