Failed to allocate receive buffer problem

[Alex Liptsin]

Hi.

I have a problem that when running a ping (or any other traffic) over IPoIB port,
Traffic fails after some time.
At destination server DMESG I see that errors:

I work with FreeBSD 9.1.

Is it a bug or some configuration issues?

Thanks.
