I have clr stored procedure that calls a Webservice method. Webmethod in turn call a com object .. and do some processing on a remote Unix server. When I invoke webmethod by it self it works fine. But when called from the CLR I get the following exception.. What am I doing wrong ?

Msg 6522, Level 16, State 1, Procedure PrintOa, Line 0
A .NET Framework error occurred during execution of user-defined routine or aggregate "PrintOa": 
System.Security.HostProtectionException: Attempted to perform an operation that was forbidden by the CLR host.
