Apache “MaxClients exceeds ServerLimit”: Fix MaxRequestWorkers and ServerLimit on cPanel

The warning means Apache's worker limit (MaxRequestWorkers, called MaxClients before Apache 2.4) is set higher than ServerLimit allows, so Apache lowers it at start-up. On cPanel, change both values in WHM > Service Configuration > Apache Configuration > Global Configuration, not in httpd.conf. With the event or worker MPM, ServerLimit × ThreadsPerChild must be at least MaxRequestWorkers; with prefork, ServerLimit must be at least MaxRequestWorkers.

cPanel “sshd has failed, please contact the sysadmin”: Causes and Fixes

This alert comes from cPanel's service monitor (chkservd) when it cannot reach the SSH service. First check whether SSH really is down: systemctl status sshd. If it is stopped, test the configuration with sshd -t, fix the error it shows, and start it with /scripts/restartsrv_sshd. If SSH works but the alert continues, the monitor is probably checking the wrong port after a port change. Use your provider's console if you cannot log in at all.
