What is a reason of 'No buffer space available' error? Which buffer should I increase to avoid this? My PPP interface is very unstable, it locks up with high traffic volume and ping issues this error. This is PPP over TCP over Ethernet (with traffic shaper) both sides run FreeBSD 4.4-STABLE and stock pppd. These lockups are 100% reproducible with ping -f. After some period of time no packets can pass and even if I stop ping, the interface is dead forever, until pppd is stopped and restarted manually. However, interface stays 'up'. These are options of pppd: netmask 255.255.255.255 local debug kdebug 1 115200 lock asyncmap 0 nodetach mtu 576 mru 576 nodeflate nobsdcomp persist The other side has the same options plus assignment of IPs (ipv4). # netstat -m 51/192/16384 mbufs in use (current/peak/max): 51 mbufs allocated to data 1/8/4096 mbuf clusters in use (current/peak/max) 64 Kbytes allocated to network (0% of mb_map in use) 0 requests for memory denied 0 requests for memory delayed 0 calls to protocol drain routines Eugene Grosbein To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
