Arpwatch / Node_exporter(?) generating a notification mail every minute

[lightningbit]

Hi,

I just upgraded my pfsense installation from 2.4.5 to 2.5.0

I reinstalled the node exporter package to prepare for using Prometheus and Grafana soon.
but now I get a mail every minute

• with this in the subject :

(myshostname) - Arpwatch Notification : Cron <root@(myhostname)> /usr/bin/nice -n20 /usr/local/bin/python2.7 /usr/local/share/pfSense-pkg-node_exporter/interface-collector.py

and in the mail body :

X-Cron-Env: <SHELL=/bin/sh>
X-Cron-Env: <PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin>
X-Cron-Env: <HOME=/root>
X-Cron-Env: <LOGNAME=root>
X-Cron-Env: <USER=root>

nice: /usr/local/bin/python2.7: No such file or directory

I've looked around the settings to suspend the mailalerts but could not find where to do it.
in the arpwatch settings : arpwatch is set to disabled

Also the node_exporter is disabled for now

But the mails keep coming.

Anyone who can assist or shed some light?

Thanks,
