Hi All,
I've noticed some pretty intense memory usage out of my Vyatta router:
[EMAIL PROTECTED]> show system memory
total used free shared buffers cached
Mem: 255268 250956 4312 0 142652 32900
Swap: 0 0 0
Total: 255268 250956 4312
I know the spacing is a bit off, but free memory is only 4312 bytes.
Examining the process memory usage under the shell shows that the xorp
daemons are using the lions share of the memory:

This router really isn't doing a whole heck of a lot, OSPF is by far the
most resource intensive process on this router. I've included the config as
an attatchment. Any insight would be much appreciated.
Thanks,
Nick
