The chkservd process attempts to connect to “127.0.0.1:143” in order to validate that this service is functioning. If you blocked connections with iptables or the “Host Access Control” interface in WHM, this failure may be a false positive.
To resolve this issue, either open the firewall to allow connections as the root user to “127.0.0.1:143” or disable checks for this service in WHM’s “Service Manager” interface with the “Configure Monitor Settings” link below.

Hey there! If this is still an issue, I would recommend checking /var/log/maillog on the system to see if you are experiencing some type of email authentication attack on the system. If there are a large number of users trying to access the IMAP service this can cause it to appear down for the service monitoring check, resulting in this failure notice and the tool not being available.
Let me know if you see anything in that log and we can go from there.
