[RESOLU] - Netdiscovery stalled with high CPU usage

GLPI 9.5.6 / Fusion Inventory 9.5+3.0
My netdiscovery tasks never work. They stay on going for a very long time in Fusion GUI.
In agent log, I says :
[Wed Jan  5  11:08:00 2022][debug] scanning block <startIP>-<endIP>
and nothing else.
The agent consumes a lot of CPU  (50% to 100%) for a long time, even for a small IP range (20 IPs) without doing apparently anything.
SNMP net inventory tasks are working fine
Any idea ?

Can you change the debug parameter on your agent and try again? You'll probably be able to have more intel.

Re: [RESOLU] - Netdiscovery stalled with high CPU usage

debug=2 (3 is for debug of SSL  which is not activated yet) in agent.cfg gave extra info below.
But nothing which could explain the behavior

Bon. Pb réglé. Il y avait une erreur dans la plage IP qui était énorme du coup.

Re: [RESOLU] - Netdiscovery stalled with high CPU usage

Just in case some english reader come here : Avoid using large IP adresses with fusion agent. Multiple /24 is fine, more can consume a lot of CPU.
