What kind of operation the stored procedure is doing?

I think the problem won't be caused by simultaneously calls of the stored procedure itself (SQL server will process them in different user sessions) but what the procedure does may lead to dead locks when accessing/modifying the same table data at the same time. You'll have to ensure, that the procedure doesn't do the same actions at the same time for 2 different users. May be you can use a small table to flag the operations in progress so that any running instance of that procedure is able to synchonize it's actions.
