How License Limits Work
The domain limit only refers to top-level domains. Subdomains are unlimited. Aliased/parked domains, which do not use their own virtual hosts, also do not count toward the limit. Any domains that exceed the specified limit will result in a 403 error (or, in cPanel and Plesk environments, will revert to Apache).
The number of workers in the license description indicates how many LiteSpeed processes will be spawned - the number of processes that do general server work. Examples of the work done include routing requests, SSL decryption/encryption, caching, rewriting, serving static contents, etc.
A server can have any amount of RAM up to the RAM limit for that license type. LSWS will share this RAM with all other processes like normal. Using a license on a server with RAM that exceeds the specified limit will result in an error.
