I'm having a problem executing a SQLCLR function: this function  
calls a web services that processes a query to a  data base and 
returns a table to be used in a stored procedure. In a  low 
concurrency scenario (not to many clients connected), the function 
returns  correctly, however when the concurrency level is increased 
we  have a SQLCLR command execution problem (all the SQLCLR 
processes hangs), making the server unavailable to all web services 
processes.

At first we thought the problem could be the SQLCLR, since the web  
services is 100% available, all the time. We monitored to come  to 
this conclusion. Do you know of some SQLCLR bug?

Could someone help me with this? I'm in a difficult situation with  
my client, considering that we defended the MS SQLServer technology  
and now it's not working properly.
