Problem with pptp

[gull]

Hi! I've Openbsd 4.4 with default kernel and connection to Internet by pptp. Problem is sometimes it connects but sometimes doesn't. But in most cases when it connects it pings any host with message:

ping: sendto: No buffer space available
ping: wrote ya.ru 64 chars, ret=-1

Here some files:

1. hostname.fxp0

dhcp NONE NONE NONE
!route add -host vpn.provider.net 10.129.0.17
!route add 85.21/16 10.129.0.17
!route add 195.14.32/19 10.129.0.17
!route add 10/8 10.129.0.17

2. hostname.tun0

!/usr/sbin/ppp -ddial corbina >/dev/null 2>&1

3. ppp.conf

default:
set log Phase Chat LCP IPCP CCP tun command
disable ipv6cp
corbina:
set device "!/usr/sbin/pptp vpn.provider.net --nolaunchpppd"
set timeout 0
set authname <login>
set authkey <password>
set login
set ifaddr 85.81.225.18 10.129.0.17/0
add! default HISADDR

4. /var/log/daemon
