I am receiving in my SQL Server environment this messages in the SQL Server Logs: WARNING: EC 20c88098, 4 waited 300 sec. on latch 42cad3f0. Not a BUF latch. Right now we have problems with slowness in an application that runs a stored procedure from this server every time they click a button. Like 20 users run this stored procedure but it takes too long in the application interface to do this stored procedure. I really don't understand this message can someone understand it?
