The K2ETS repeater(s) [ 2M-27274 & 220-27273 ] are running on a Pi-2 under Debian as a dual node system. I'm using a Class10 SD card.

We've had an audio issue for more than a year now, and I'm unable to track down the cause. [ sample attached ]

After a re-boot, the audio is perfect. Over the course of a month or so, small audio interruptions begin to appear, becoming actual ' clicks '. It appears that the

processor is becoming overloaded, and the DSP is affected. Members have named it our ' Galloping Ghost '.

Sometimes, just clearing the log file and re-starting asterisk fixes it, but usually a re-boot is required.

I'm stumped. I plan on re-installing Debian, and going to a Raspberry Pi-3 in the spring.
