Services status unknown after update 24.10.14 from 24.10.13

[rmorandell-pgum]

I have this problem on two different systems/pollers after upgrading the pollers centreon-engine and centreon-connector from 24.10.13 to 24.10.14.

Only the plugins/commands without perl connector was going all the time. After a restart is working for a while until next time, when suddenly all checks go to (Process Timeout)

I can see this error in engine log:

[commands] [error] [967680] unknown query type: 0
[commands] [error] [967680] recv query failed: command_id(2233) not found into queries
[commands] [error] [967680] time out of id=1480, command_id=1480 start_time=Tue Dec 23 10:28:55 2025: , end_time=Tue Dec 23 10:29:55 2025: , exit_code=3, exit_status=timeout, output='(Process Timeout)'

After a downgrade to 24.10.13 the problem has gone away again. I would like to add that other pollers with the 24.10.13 engine on the same system never had this problem.
