FWIW, in load testing of a large Web app using SCGI, under PLT 4.2.5
with CGC, we haven't yet found any memory leaks. The process size would
grow initially and then plateau at a reasonable size.
A general good fallback plan, whatever your technology (Racket, or
something else), is to retire server processes after a while. If your
system is architected to scale using load-balanced servers, which is a
good idea anyway, implementing retiring is easy.
(Have a flag or time-to-live value for each server/process, stop sending
new sessions/connections to the retired server/process, and exit the
server/process once no more active sessions/connections; start new
servers/processes as needed.)
