Hi, My nfsserver is stable, but sometimes (at least 1 or time per week) the service just hangs (ONLY the service nfsserver) When this happens, "rcnfsserver stop/start/restart/reload" or "exportfs -a" don't work (just hangs), can't do a "cat /proc/fs/nfs/exports" or "cat /etc/exports" (hangs to) and cpu load is very high (but all others services on server is OK) and all clients hangs up (home's users is a nfs mounted folder...) My /var/log/messages reports only this: saobkp rpc.statd[1152]: Can't callback saobkp (100021,4), giving up. The last resource is a hard boot (power off) !!! My configuration: #saobkp is the nfsserver #Server Suse 9.0 #Linux saobkp 2.4.21-273-smp4G #1 SMP i686 i686 i386 GNU/Linux #nfs-utils-1.0.6-114 # /etc/exports /home *(insecure,sync,rw) /cdrom *(insecure,sync,ro) # /etc/hosts 127.0.0.1 localhost # special IPv6 addresses ::1 localhost ipv6-localhost ipv6-loopback fe00::0 ipv6-localnet ff00::0 ipv6-mcastprefix ff02::1 ipv6-allnodes ff02::2 ipv6-allrouters ff02::3 ipv6-allhosts 172.22.50.6 saobkp.sao.jamef saobkp # eth0 = 172.22.50.1 # host saobkp saobkp.sao.jamef has address 172.22.50.6 # /etc/sysconfig/nfs USE_KERNEL_NFSD_NUMBER="10" STATD_HOSTNAME="saobkp" # CLIENTS CONFIGURATION uses autofs (automount) # /etc/auto.master /server/u /etc/auto.u # /etc/auto.u * -fstype=nfs nfs:/home/u/& # And "host nfs" nfs.sao.jamef has address 172.22.50.6 What is wrong?
