Ironically, I have had no problem when manually invoking the program and
NOT running it in daemon mode. Invoking it with :
ntop --user ntop --db-file-path /var/ntop --interface br0 --trace-level 3 --https-server 0 --http-server 3001 --disable-schedyield --no-fc
Has had it running for quite a while without any issues. Of course you'll want to specify any other interfaces you want monitored besides the bridge. You just access it with http as opposed to https
