Hello Ole, I think the move to 6 buffers(it has only a small memory penalty) should suffice, because there are no module functions that might have more than 6 parameters.
If I remember correctly, I have also patched the kamailio_3.0 branch, so if you are using 3.0.0 you might already have the patch in place so you can remove the if's from the cfg.

For now I've made a workaround in the config with some "if" constructs. Thanks, Ole
