Hey,
I am using tbnl 0.9.10 and sbcl 0.9.11. I have some functions which generate HTML content using cl-who etc. I have run then through heavy testing and they work fine in the REPL (no memory leakage).
As soon as I am calling them via tbnl/mod_lisp the lisp memory usage jumps tremendously. I ran the ab2 benchmark (100 requests with concurrency 1) and the memory usage went from 50Mb to 300Mb+. It then starts swapping.
Is this a known problem or am I doing something terribly wrong ?

I'm not aware of any memory leaks in TBNL and it's hard to say if you're doing something wrong without seeing your functions. As a simple test I'd suggest running the same example with another Lisp that is known to work with TBNL, like CMUCL. What you're seeing /might/ be related to SBCL's threading implementation. I don't know, I usually don't use SBCL.
Good luck, Edi.

Can you try and benchmark a small function and see if the problem is still there? If so, then trim parts of it until you get either: 1. a function that doesn't leak, in which case you can pinpoint where the problem lies; or 2. a small function that still causes problems, which you can post here.
In short: troubleshoot a bit more! :)
