One of my KiwiSDR restarts about once or twice a week. /var/log/syslog shows something like this from the event:

Trying to figure out if this is a software issue or something specific to my setup. Has anyone else seen this behavior?

    The next release will send some additional debug information to the log when this panic occurs. From the backtrace the crash seems to occur when DRM mode is started.

    Okay, v1.384 is out and should include additional info in the log when this panic happens again. It will tell us which stack type task allocation has run out: normal, large (for waterfall), huge (for DRM).

    Thanks, updated to v1.384. Will report when I see this event next time.
