Minor Description
I have 3 identical servers running Proxmox VE 6.3 conforming a Cluster.
Discovery.php fails to detect Node 1' OS and Proxmox and set it as Standar Linux. Also discovery takes too long to work.
Detection of Nodes 2 and 3 works great and the running time of discovery is considerably short than node 1
# /opt/observium/discovery.php -m os -h node1

They have the same sysObjectID and sysDescr.
SNMP config is the same on all (managed by puppet). SNMPD service was restarted several times with no change in behavior of discovery.
BTW: when try to debug the output of discovery I get:
# /opt/observium/discovery.php -d -m os -h node
|
DEBUG!

Ok, this is still strange.
By unknown reason, your server stop respond with timeout on snmpbulkwalk.
We not seen before such troubles on any linux hosts.
Now I can only advise set different max-rep value (ie around 30) or complete disable snmpbulk by set maxrep to 0 (as you done for node1).

Hrm, you was set maxrep 100 manually before?
(we not use such value for linux hosts).
I think than this is main trouble for you, remove this value for devices (default is 10 and this value is quite enough for linux hosts).

For future releases snmpbulkwalk complete disabled in os detect.
Fixed in r11691.
