We are frequently getting "Service Check Timed Out" alert for DB checks.

We are able to run checks through CLI. The service throws the "service checked timeout" error for a small duration of time like 4-5 mins and then again going to its normal state. We are observing that the errors are occurring quite frequently. Please help us in getting this resolved.

Have you tried bumping out your timeout to see if it will still get through? Sounds like you're having some networking issues between the XI server and the DB server. To add a longer timeout edit the command that the service is running, either in CCM > Services > "service name" > at the end of the arguments add "-t 30" or however long you want it to keep the socket open. Or you may need to change it in the template if there is nothing defined in the first page of the service's config. To see it's template and edit that, you will need to click the Templates button on the service's config page, and find the service template selected there.
