More or less as the title says. I am running IP-Symcon 4.00, 02.08.2016, 198269bb5775 on a Rpi without any issues. When opening the web-app and viewing the historic data of a variable, IP Symcon crashes after changing the timespan of the graph. It is not completely reproduducable (as in, it does not happen all the time) so there is some other factor involved. Logs do not give anything that seems to help in finding the cause.
Restarting from console gives no problems and it runs again, but it is an issue I suppose.
