Dear list: As my traffic has increased lately I have occasionally noticed my emi2 smsbox going "power-hungry" as well. It goes from an insignificant CPU load to 96-99%, and stays there. There's no significant impact on the performance but that's probably because I'm nowhere near using the machine's capacity right now. I'm handling only 10-50 SMS per minute right now, on a dedicated line to the operator.
I'm manually restarting the boxes when I notice it, but if anyone finds a better fix, please announce to the list. (Yes, I saw the clever little script that checks for high CPU and restarts automatically, I'm hoping for a better one than that.) I was following the discussion but didn't see much resolution, it seems real to me. I hope the issue is followed up...
