sudo /etc/init.d/weewx stop will stop the current running service but if you have other instances running, for example WeeWX directly, sudo /etc/init.d/weewx stop will have no effect as WeeWX is not running as a service. When running WeeWX directly you need to stop the execution using a control key sequence (CTL-C) or list the running WeeWX processes with ps -aux|grep weewx and then use the Linux kill command to kill the process.
Whenever you do a lot of stop-starting, running services/running directly and odd things (apart from odd pressure values :) ) are happening it can be because there is more than one instance of WeeWX running. If you look at the log you can usually see it by there being more than one process ID number against WeeWX at any one time. Well if your relative pressure is set correctly I am out of ideas on how to fix this. I am not convinced the driver is wrong but I guess it is possible. Really need someone who understands the driver operation and the 2813 to take that further.
