I moved this thread from our Developer Discussions thread, because it does not appear to address a development issue.
cpsrvd is the cPanel daemon. Are you receiving these e-mails only once a day or so, or more often? Are you still able to access the WebHost Manager and cPanel? As has been suggested, if you are only receiving the message once a day, it may be due to updates and therefore may not be a cause for concern.
If it is happening more often than once a day, and/or you are not able to access the WHM and cPanel, I recommend that you submit a ticket so that we may investigate the root cause and fix it for you.
