FreeBSD: ping6: sendmsg: No buffer space available

Shadow Hawkins on Monday, 28 May 2007 21:04:34

Hello, I've recently set up a SixXS Aiccu IPv6 tunnel to one of my FreeBSD 6.2-STABLE systems. Everything works well for a while, but after transferring a large amount of data over IPv6, the connection fails and I cannot connect to any IPv6 hosts through the tunnel. I get the following message when using ping6 to any internet host: (when pinging www.sixxs.net) ping6: sendmsg: No buffer space available ping6: wrote noc.sixxs.net 16 chars, ret=-1 Any thoughts on what could be wrong?

FreeBSD < 7 is according to the developers broken in various ways with respect to IPv6. According to them, the real route to go is to upgrade to 7-CURRENT...

It doesn't seem to be fixed in 7.0-RELEASE... I get exactly this behaviour on a fresh 7.0 RELEASE install.

I had this problem once with the em driver, what is your exact uname output? Maybe it has been already fixed. ATM , with -p4 all is working fine here. =:)

I have the same problem with a 6.2-STABLE of 14 April 2007. I got the tunnel two days ago, and I had to restart aiccu two times (nearly every 24h from start) to keep it working. I transfered very few bytes, so it seems a time-related issue in my case. Maybe transferring more data would trigger it sooner. I don't think FreeBSD 6 is broken in such a way, probably there is already a fix or a tunable to be set. UPDATE: it seems fixed with a 6.2-STABLE of 18 July 2007 (the tunnel is up for 24h now).
