Some further info. I have noticed when I log in after being away and WSJTX appears frozen, it is using 100% processor. If I leave it for a few minutes minutes it eventually recovers. However while frozen like this it stops reporting to PSK reporter.
I have a low power processor: Intel J5040 from 2019 (10W passively cooled mini ITX board). WSJTX usually uses about 7% CPU and jt9 uses about 12-20% when everything is normal. I usually use the USB audio "alsa_input.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00.iec958-stereo" for the rig, but it also freezes using the pulseaudio default with analogue 3.5mm cable. Freezing also happens when I disable the rig connection and just use a stand alone shortwave radio. I haven't seen freezes with interactive use, or when it is running in the background and I am using the computer. Any ideas why CPU is pegged at 100% when I've been away for a while? Perhaps this happens to other people, but with a faster CPU the recovery is quick enough they don't notice.
