I have suddenly found there are no service status signs showing for exim, ftpd, httpd, mysql, named on WHM's Service Status webpage for several days. And there is always no JSP service status showing for Tomcat JSP Server. I have selected to monitor all the above services. They should show the service status signs on on WHM's Service Status webpage. I'm using a VPS box now. I don't know what has caused these. It's my first time to come across with this situation. Is it something to block these services' monitors to save the server memory?? Please help! Thank you very much!
