[Openswan Users] pluto eats RAM

[Matthias Lembcke]

Hi there!

I've got a problem with Openswan 2.4.4 running with Kernel
2.4.28/KLIPS-patch. 6 tunnels are established on this box,
the clients have a short rekeying interval (2m) - after
3 - 4 days pluto consumes 200MB RAM till running out
of memory. Then the kernel begins to kill processes:

__alloc_pages: 0-order allocation failed (gfp=0x1d2/0)
__alloc_pages: 0-order allocation failed (gfp=0x1d2/0)
VM: killing process ipsec
__alloc_pages: 0-order allocation failed (gfp=0x1d2/0)
VM: killing process sh
__alloc_pages: 0-order allocation failed (gfp=0x1d2/0)
VM: killing process sh


I don't understand this, at the beginning it takes only
30 MB and it takes a long time till it rise.

Regars,

Matthias
