Cross" Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG This is yet another problem that we have run into here. If you check the digest for -hackers it was reported awhile ago (mike smith even cc-ed it to security since it may have been a kernel stack overflow) . Anyway, the problem is that IRIX defaults to 32K packets on TCP NFSv3 mounts, and 16K on UDP NFSv3 mounts. I recommend using UDP and setting rsize=8192, wsize=8192 in your amd maps (as we do now, no problems at all). -- David Cross | email: crossd@cs.rpi.edu Systems Administrator/Research Programmer | Web: http://www.cs.rpi.edu/~crossd Rensselaer Polytechnic Institute, | Ph: 518.276.2860 Department of Computer Science | Fax: 518.276.4033 I speak only for myself. | WinNT:Linux::Linux:FreeBSD To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
