Binary Logs

Hello all, i tried to search in this forum for a solution regarding a problem i have with cron. It seems that it is filling up my binary log so the server crashes. fills 250mb in a couple of minutes
I have deleted the crons in wp_options but it seems that the culprit returns and repopulates the cron table.

this is a copy what i have in the cron table
