Hello all, I have 2 software probes. One is on a datacenter VPS and the other at home (runs on Proxmox). The one at home keeps going to disconnected. The probe is Debian 12. Probe version is 5080-1. This machine has v6 as well - so I was thinking maybe something with temp/privacy addresses getting reaped but no, I only have one good old EUI-64 address on there. (Knock on wood) - no other VMs on my Proxmox machine have any issues like this. The only thing that looks remotely related (and this happened a bit before Nagios sent out an alert) is this: Jun 17 12:34:41 atlas-probe ATLAS[123749]: /usr/local/atlas/bin/ATLAS: 99: kill: No such process Jun 17 12:34:41 atlas-probe ATLAS[123749]: no ssh client matching . cleanup state files. for next restart Jun 17 12:34:41 atlas-probe ATLAS[123749]: RESULT 9006 done 1718642081 bc2411ca94c6 no reginit.vol start registration Jun 17 12:34:41 atlas-probe ATLAS[123749]: /var/atlas-probe/status/reginit.vol does not exist try new reg Jun 17 12:34:45 atlas-probe ATLAS[123749]: Ping works Jun 17 12:34:45 atlas-probe ATLAS[123749]: /usr/local/atlas/bin/ATLAS: 92: kill: No such process Jun 17 12:34:45 atlas-probe ATLAS[123749]: start reg Jun 17 12:34:45 atlas-probe ATLAS[144349]: ATLAS registration starting Jun 17 12:34:45 atlas-probe ATLAS[144349]: REREG_TIMER 1718416507 expired now is 1718642085 Jun 17 12:34:45 atlas-probe ATLAS[144349]: REREG_TIMER_EXPIRED go re register REREG_TIMER 1 , now is 1718642085 Jun 17 12:34:45 atlas-probe ATLAS[144349]: REGHOSTS reg03.atlas.ripe.net 193.0.19.246 2001:67c:2e8:11::c100:13f6 reg04.atlas.ripe.net 193.0.19.247 2001:67c:2e8:11::c100:13f7 Jun 17 12:34:45 atlas-probe ATLAS[144349]: ssh -p 443 atlas@reg03.atlas.ripe.net INIT Jun 17 12:34:48 atlas-probe ATLAS[144349]: Got good controller info Jun 17 12:34:48 atlas-probe ATLAS[144349]: check cached controller info from previous registration Jun 17 12:34:48 atlas-probe ATLAS[144349]: NO cached controller info.

I assume there is some debug I can crank up ? Just going to reboot this for now to get it happy and get Nagios to shut up. Thanks.
