Getting SSL error. Some I/O error occurred. in Other Problems Posted June 13, 2013 · Report reply I'm running one script that allows a user to login with their username and password, then click the log out btn to log out of the system. I run 50 users with a ramp in of 1 evry 30 seconds for a total run time of 30 mins. When I reach 29 active users I start getting SSL error. Some I/O error occurred and when I manually enter the username and password on another device while the load is running I can't log in. It just spins. Could you tell me what may be going on and how could I fix it?
