That's the version that's included in the debian package python-serial. Looking through the pyserial change log <https://github.com/pyserial/pyserial/blob/master/CHANGES.rst>, I don't see any obvious patches for memory leaks between v3.2.1 and v3.4.
The only major difference (besides API details) I see between the Ultimeter and the Vantage drivers, is that the former uses the method readline(), instead of read(), but it's hard to see how that would lead to leaks. You can try upgrading to v3.4 and see if that helps. First remove the Debian package, then use pip: *sudo apt remove python-serial* *sudo pip install pyserial* -tk On Wed, Feb 6, 2019 at 7:19 AM Steve2Q <stev...@gmail.com> wrote: > My version is 3.2.1 > > -- > You received this message because you are subscribed to the Google Groups > "weewx-user" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to weewx-user+unsubscr...@googlegroups.com. > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
