Are you running a cronjob which is messing with it ?
Check sudo crontab -l and /etc/crontab and /etc/cron.d
When / how often are the ipsets being changed/added ?
Install "psacct" or acct package and enable accounting and see what's running
when that happens. Or move ipset out of the way (or replace it with a
shellscript to run sleep 999) and see what breaks.
