Dormant services

This setting configures the system to unload idle services from memory after up to ten minutes of inactivity, and then loads listening devices that correspond to it. This setting reduces memory usage, but delays responses from dormant services. When you enable this setting for a service, that service will immediately enter dormant mode whenever you reboot your server or restart the service.

You can enable this behavior for the following services:

  • cpdavd — cPanel's WebDav daemon.
  • cphulkd — cPanel's brute force protection daemon.
  • cpsrvd — The cPanel & WHM service manager daemon.
  • dnsadmin — cPanel's DNS management daemon.

    Warning:

    If your server uses a custom dnsadmin plugin, you must disable dormant mode for dnsadmin.

  • spamd — The Apache SpamAssassin™ daemon.

The system enables this setting for each service by default.

Note:

Tailwatch checks do not prevent or interrupt dormant mode.

 

Maintenance cPanel RPM Check

This setting allows you to specify whether the system runs the /scripts/check_cpanel_rpms script to check cPanel RPMs for problems during nightly maintenance. If these checks encounter problems, the system sends a notification to the administrator. For more information, read our The check_cpanel_rpms Script documentation.

This setting defaults to On.

Warning:

We strongly recommend that you do not disable this setting. If you disable this setting, the system does not check existing RPMs for problems during updates or maintenance. This could leave your system vulnerable to unnoticed tampering or other risks.

 

Maintenance cPanel RPM Digest Check

Note:

This setting is only available if you have enabled the Maintenance cPanel RPM Check setting.

This setting allows you to specify whether the system runs a digest check against existing RPMs during nightly maintenance. This check ensures that RPM files are not corrupt, and that nothing has tampered with them.

If you disable this setting, the system runs the /scripts/check_cpanel_rpms script with the --no-digest option. For more information, read our The check_cpanel_rpms Script documentation.

This setting defaults to On.

Important:

We strongly recommend that you enable this setting. If you disable this setting, the /scripts/check_cpanel_rpms script only validates file sizes, and files may change without detection.
