Pinched from the `Common error messages' section of the docs:

10.3 "Out of space for port forwardings"

PuTTY has a fixed-size buffer which it uses to store the details of all port forwardings you have set up in an SSH session. If you specify too many port forwardings on the PuTTY or Plink command line and this buffer becomes full, you will see this error message.

We need to fix this (fixed-size buffers are almost always a mistake) but we haven't got round to it. If you actually have trouble with this, let us know and we'll move it up our priority list.

If you're running into this limit, you may want to consider using dynamic port forwarding instead.

This has now been corrected: PuTTY uses a dynamic structure to store port-forwardings.
