bsnmpd is crashing when using Zerotier

[virusmoere]

Hi,

the bsnmpd daemon is crashing when using any zerotier interface. I can reproduce this on two appliances. I already tried to change the bind interface to only LAN, but it is still crashing. I am using the service for Naemon interface monitoring.

I've had this same problem with bsnmpd for quite a while and I just now narrowed it down to having ZeroTier enabled.  As soon as I disabled ZT, it stopped crashing.  Searched and it led me here, so I'm glad it's not just me.

Currently using OPNsense 18.1.10 on ESXi 6.5, though it's not a new problem, goes at least a few versions back.

Next OPNsense brings netsnmp Plugin, perhaps it's more stable with ZT

Thanks!

It is working fine with netsnmp now.
