There is your problem, NEED COLLECTION (__gc). GC is good for
tracked-memory-only resources, not that good for others ( including
objects which hold a lot of memory unbeknownst to the GC ). You may
solve this with GC tunning, but I've had some similar problems, in Lua
and other GC languages and I have ended up having to manually manage
them ( I normally have an idempotent close() method, influence by Java
naming, which I call on __gc()just in case, and now on __close() too,
as you say your objects are ocasionally updated hence neading
"destruction", you will probably be better trying to encapsulate their
managemente there.
