Odd CPU performance pattern

I hooked up Zabbix to our existing Mango 3.7.7 installation and noticed that the CPU usage was oddly high and following an odd pattern:
On every hour and half hour, CPU utilisation drops to 3% for 6 minutes and then ramps back up to 60%.
The timing is actually three minutes before the 00/30 mark until 3 minutes after.
Looking at the mango process in htop confirms the behaviour.
The mango installation isn't particularly heavy, 86 data points.
Server CPU info: 2x Intel Xeon CPU E5-2630 v3 @ 2.40GHz
