hello,
When a calls come to the system and goes to the queue, my system seems to be hang.
After tracking the system i figured out that op_server.pl is taking max. cpu time. More the call in the queue more will be the load. I have attached the output of top as below.
top - 14:28:47 up 20 min, 4 users, load average: 3.05, 2.48, 1.44e
