interface/if_octets-bridge0.rrd: Cannot stat

[huberte]

I received from

Cron <root@freenas> /bin/sh /root/save_rrds.sh

this and understand nothing (but it may come from a network issue ?)

Code:

tar: collectd/rrd/localhost/interface/if_octets-bridge0.rrd: Cannot stat: No such file or directory
tar: collectd/rrd/localhost/interface/if_octets-epair0a.rrd: Cannot stat: No such file or directory
tar: collectd/rrd/localhost/interface/.if_octets-bridge0.rrd: Cannot stat: No such file or directory
tar: collectd/rrd/localhost/interface/.if_octets-epair0a.rrd: Cannot stat: No such file or directory
tar: Error exit delayed from previous errors.
