This machine serves: 4 SGIs, 1 Suns, 2 HPs, 2 Linux :-(, 4 Apples and about 100 PCs. Among the PCs there are 4 BSD 2.2-STABLE machines and only one has severe problems. This is a: PPro 200 with 2940 and one SMC8416C (== EtherEZ on ISA BUS). When mounting a nfs drive from the above mentioned server, it takes between 2 and 60 minutes and all nfs activities get frozen. I have some error messages in dmesg: When mounting with "-v -o -i,-s" I get: nfs server p-h:/people: not responding nfs server p-h:/people: not responding nfs server p-h:/people: not responding nfs server p-h:/people: not responding nfs server p-h:/people: not responding nfs server p-h:/people: not responding nfs server p-h:/people: not responding nfs server p-h:/people: not responding nfs server p-h:/people: not responding nfs server p-h:/people: not responding nfs server p-h:/people: not responding Out of mbuf clusters - increase maxusers! nfs server p-h:/people: not responding When mounting with "-v -o -i,-s,-T" I get: impossible packet length (1516126026) from nfs server se:/people receive error 27 from nfs server se:/people impossible packet length (808342880) from nfs server se:/people receive error 27 from nfs server se:/people impossible packet length (861948492) from nfs server se:/people receive error 27 from nfs server se:/people impossible packet length (721158501) from nfs server se:/people receive error 27 from nfs server se:/people I have changed the ethernetcard already and on the same wire there are other machines which work great... -Andre
