>>I have a tcp/ip server program that I've tested extensibly, and if I put a breakpoint at 119 it will never be hit unless I put 10 clients messaging with the server. Then there is a problem almost immediately. The problem is that under this high load of 10 clients hitting the server every 1/2 second:

>>e.message = "Too many arguments specified for pr_step_selectlast"
>>pr_step_selectlast expects one input and pr_step_updatecompleteness expects two inputs.
>>pr_step_selectlast was the last stored procedure run, so why is it getting confused with the current stored procedure = pr_step_update completeness?
