Litespeed attempts to make starting up very fast, and it does so by initializing Rails framework in a parent process, then doing the fork. That way, all that disk-scouring to find all the rails files, which takes about 6 seconds of heavy iowait, is only done once.
However it also means that any connections you initialize will also be shared among child processes.
Database connections - the LSAPI parent process explicitly disconnects after loading, so they'll be re-initialized for each child.
Memcache connections you need to do yourself. I do so at the bottom of my environment.rb (I'm using memcache-client, which sets a global CACHE):
