Cron/index.cgi high cpu usage

I have a pretty fresh install of Virtualmin with only single virtual server. Everything seems to be snappy but with one exception. When I go to Cron Jobs view it takes forever to load (about 1 min). I’ve traced it to cron/index.cgi which is using 100% cpu while view is loading. I have not added any crons yet… I’ve switched to legacy theme but same issue. I don’t see anything suspicious in the logs… Do you have any clue what could that be?
Thanks
