I installed munin on my ubuntu server. It's showing my 'inode table usage' spiking every morning at 8am. It then rapidly curves down and settles over the course of several hours. What might cause this?

enter image description here

I thought it might be something running in /etc/cron.daily but this was set to run at 6a.m. and I've changed it to 4am. The spike remains at 8am. I also enabled cron logging, but can't see anything getting launched at 8a.m.

It's a virtual server hosted by memset. Could it be caused by something happening on the virtual host?
