Nagios does not run any check anymore

[MAD]

Sorry if that question was already answered but I wasn't able to find a solution.

I have Nagios v3.0.6 running some test to check the access to some URL and supervising some local metrics (cpu load, disk space...). For some reason I can't figure out, Nagios stopped running the test and re-scheduled them to June the 6th instead of running them every 5 minutes. I tried to restart it and everything seemed to work fine again.... for 10 minutes and then the checks were postponed again to June the 6th.
Besides, when I restarted the server, Nagios unloaded the ndo module 10minutes after the restart.

Here is the last lines of the logfile:

Does someone know what is happening and how I could fix it?

Thank you
