Pickup issue that the dailer did not have enough processing power (cpu) .

I have installed vicibox 6.0.3 in X3250 M5 server. It was working fine about 6 months. But suddenly i see bad file descriptor error on asterisk logs. i have 24 agents who login in the server. when i give dial level more than 4 then bad file descriptor error message coming in the screen and every agent goes to waiting mode. When i reduce the dial level it is working fine. I dont get the issue. My production is getting hamper. Please help .

55 agents is way too many for a single telephony server. You'll need two to support that. Your CPU is also under powered; we recommend at least a 2.4 GHz. It sounds like you might be overloading your hardware.
