Problem with dtsrun

I am trying to execute a DTS Package from within a stored procedure, however the Execute statement hangs while running the debugger.

The sql is EXECUTE @.SP_Return = master.dbo.xp_cmdshell 'DTSRun /E /SBIGO /NPFW Data Load', NO_OUTPUT

The debugger hangs, SQL Query Analyser does not respond after exiting the debugger and MSSQLSERVER needs to be stopped & restarted.

The DTS Packages runs fine from the cmd prompt as can be seen below

Any help would be great.

Are debugging procedure in QA?

If so comment the dts package during debug there may be disconnect from DTSRun utility and debugger might be not able to handle situation properly...
