Steve, Been there and done that. These memory issues can be a pain to track down. I had one a while back and it was a case of memory usage ramping up each hour, the slope of the plot was so constant you could set your watch by it. Tracking down the culprit can be a time consuming process as I found it took a few hours from a restart before I could be sure the memory usage was on the way up, there used to be a bit of up and down after startup before the constant increases started. As Vince said one approach is to go back to a bare bones install and add things back one at a time till you find the culprit. Unless you have done anything out of the norm with your RPi I would not worry too much about winding back the operating system, start with WeeWX, its the obvious candidate.
In terms of winding back WeeWX, sure you can uninstall your extension but then you risk losing config settings. Another way to achieve the same effect is to disable services in [Engine] [[Services]], that way you keep your config and just turn services off. Just comment out/remove services for those you wish to disable, if you want to go back to a bare bones setup or want to know what services you have on top of a bare bones install have a look at/compare to the bare bones weewx.conf on gitHub <https://github.com/weewx/weewx/blob/master/weewx.conf#L365-L376>. Of course take a backup copy of weewx.conf before you start so you can easily go back to how it was before. Another approach is rather than going back to a bare bones install disable one added on service at a time until you find the culprit. You can do this one at a time or cumulatively. Remember also that even with this problem WeeWX will still be doing everything it should, so you are not losing data. It's just that WeeWX runs out of memory. My stop gap solution until I solved my issue was setting a reminder to remind me to restart WeeWX every so many days (I think it was 4). I am not a fan of forced restarts so did it manually each time.
