I’m pretty sure this is totally unrelated, but I had some issues with the interval program a few days ago (slow/incomplete page loads, inability to connect). It was caused by my rootfs being 100% full. Even though I was using a 4GB card I had forgotten to expand the pi’s file system after starting with the preconfigured SD card image. If you’re curious you can check yours from a command prompt by typing “df -h”. To expand it just type “sudo raspi-config” and choose “expand filesystem”.
