this is working to avoid the error. Some remarks for others.
1) using cache: false, within ajax call else the browser cache exploid with setintervall function
2) using Timeout function instead setintervall, setintervall will stack tasks if the focus is not on the window
3) i get problems with refreshing and showing “live” cause my file have 200.000 + lines in it and reread costs me around 1+ seconds some times.
correct me if im wrong
