Last Alive issue between the Centreon central unit and two pollers

Hello everyone,

I'm having an issue—apparently a communication problem—between my two collectors and my central server.

After investigating and conducting extensive research, particularly in the logs, I'm seeing errors when reading the socket data coming from the poller's IP. Here's an excerpt:

Central:

Poller 1:

For your information, the operating systems are AlmaLinux 8 for the central server and AlmaLinux 9 for the pollers. I installed the latest updates on 25.10.25

Could you help me resolve this issue and let me know if there are any similar cases currently?

Thank you.
