/var/log/audit/audit.log says:
type=AVC msg=audit(1408478520.792:7016): avc: denied { mmap_zero }
for pid=17977 comm="monitor-get-edi"
scontext=system_u:system_r:system_cronjob_t:s0-s0:c0.c1023
tcontext=system_u:system_r:system_cronjob_t:s0-s0:c0.c1023
tclass=memprotect
which isn't particularly readable but I would guess means that it
blocked the ocsinventory-agent from getting the monitor type. Not
sure why that is supposed to be helpful, but it also doesn't sound
fatal. And somewhat irrelevant on a normally headless server.
Does that dbus error looks serious?
