Good evening, We have a problematic FreeBSD box, which acts as nfs server and runs 5.3-RELEASE-p5 on an i386 AMD Athlon 64 3000+ (in a 32-bit mode). The purpose of the box is to supply another FreeBSD (5.2.1-RC) ftp server with more disk space. As of -p5, we have src/usr.sbin/nfsd/nfsd.c,v 1.30 2004/08/07 04:27:52. Average system load is about 2,5. The problem is, that the nfs server hangs after running for a while, like, 20 minutes. Any file operations (at the nfs mount points and below) hang on the ftp server too, making it inaccessible. The nfsd processes on the nfs server do not respond to any signals sent by `kill`, so only a reboot of the system is a temporary solution. We have ACPI enabled, NMBCLUSTERS set to 65535, SMP, debug.mpsafenet=0 and also some kern.ipc.* customizations which, as we assume, do not affect the behavior of nfsd. Everything is served via 3COM 3C940 single port, 1000baseT adapter (device sk). The whole dmesg is available at http://webart.lt/~molotov/dmesg Some file operations on the nfs server cause system panic. I didn't debug anything, because I do not have much experience in it, but I could try to do it by a request from anyone, who is willing to help. The strace utility shows that no system calls are performed by any of nfsd processes while they are inoperative. Any help or comments would be appreciated. Thanks in advance. -- Simonas Kareiva
