I'm running 1.5.1_ALPHA on my home router, and ocasionally I get errors like this:

Jun 15 20:57:41 zunix ppp[115]: tun0: Error: ip_Input: deflink: wrote 543, got No buffer space availabl

My box becomes unreachable even in LAN and I have to reboot it.
Any ideas? Something I could try?

The box used to work fine on FreeBSD.
