Hello, I am using an OpenBSD 4.0 box connected to a 2Mbit SDSL line in Germany (using user space PPP).
When pinging a host across the SDSL line, I get an occasional "sendto: No buffer space available" message: 64 bytes from xxx.xxx.xxx.xxx: icmp_seq=566 ttl=254 time=62.674 ms 64 bytes from xxx.xxx.xxx.xxx: icmp_seq=568 ttl=254 time=38.090 ms ping: sendto: No buffer space available ping: wrote xxx.xxx.xx 64 chars, ret=-1 64 bytes from xxx.xxx.xxx.xxx: icmp_seq=569 ttl=254 time=1320.651 ms 64 bytes from xxx.xxx.xxx.xxx: icmp_seq=571 ttl=254 time=35.792 ms Does this message point to a problem within OpenBSD or is this a problem with the SDSL line? Why is the ping packet not simply dropped but rather delayed? I have googled for the error message and some replies indicated that it is a problem within some ethernet card drivers, so I switched from fxp to em but the problem persists. This is the output of netstat -m in case it matters: 443 mbufs in use: 437 mbufs allocated to data 3 mbufs allocated to packet headers 3 mbufs allocated to socket names and addresses 436/552/6144 mbuf clusters in use (current/peak/max) 1248 Kbytes allocated to network (78% in use) 0 requests for memory denied 0 requests for memory delayed 0 calls to protocol drain routines Any help is greatly appreciated.
