If I understand the situation correctly, you - Are running plain-vanilla wheezy on a stock RPi; - Installed weewx using setup.py; - Are using an Ultimeter station; - Have absolutely no extensions installed (in particular, rtg has been disabled);
yet are experiencing memory growth. Please correct me if any of these assumptions are wrong. If they are correct, I'll make up an instrumented version of weewxd that will show which objects are growing in size and number. -tk On Tue, Jan 29, 2019 at 5:20 AM Steve2Q <[email protected]> wrote: > Here is syslog from shortly before the crash..
