Hi,

I have a shell script set up as an external item.  It in turn invokes ssh.  Since I installed 7.0, the zabbix server and proxies that use that external item exit altogether when that ssh command exits with code 255.

This is the log I see in the server:

  1:20240616:160731.803 One child process died (PID:18945,exitcode/signal:0). Exiting ...
   464:20240616:160731.803 HA manager has been paused
   464:20240616:160731.848 HA manager has been stopped
     1:20240616:160732.094 syncing history data...

     1:20240616:160732.206 Zabbix Server stopped. Zabbix 7.0.0 (revision 49955f1).

Tracking down pid #18945 it looks like

ssh -o PubkeyAcceptedKeyTypes=+ssh-rsa -o HostKeyAlgorithms=+ssh-rsa -o LogLevel=Error -o StrictHostKeyChecking=accept-new -i /var/lib/zabbix/ssh_keys/zb_id_rsa [email protected]

This external item has been in place since 5.x, this behavior is new in 7.0
