High CPU usage

[Koc]

Hello.

I've setted up jobqueue

%crontab -l
*/2      *       *       *       *  /usr/local/bin/php -f /vhosts/new.ololo.ru/new/site/apps/ololo/console jobqueue:run -e prod

When it runs ps aux says

USER   PID %CPU %MEM   VSZ   RSS  TT  STAT STARTED      TIME COMMAND
new  55176 84,3  1,6 405124 264232  ??  RsJ  18:12     1:01,78 /usr/local/bin/php -f /vhosts/new.ololo.ru/new/site/apps/ololo/console jobqueue:run -e prod

jobqueue eating until 90% of CPU. There is 4th cron sheduled tasks (swiftmailer:spool:send runs every 3 minutes, others run only at night).

What additional information could I provide for you to getting advice what to do?
