Chronograf 1.4 high memory usage (Ubuntu 16.04)

Hi, since very recently Chronograf (1.4.4.1) tends to exhibit relatively high memory usage (3GB RSS) until restarted. That’s almost as much as my Influxdb production instance. Is there a way to debug this and see what the memory heap’s used for? I don’t see any memory profiling options in the chronograf command line.
