This server running 6-Stable Last update (after crash :-( ) 23 september. I've very strange problem, after some days I got this kind of message on syslog nfs kernel: Connection attempt to TCP MY_NFS_IP_ADDR:111 from MY_NFS_CLIENT_IP_ADDR:43385 flags:0x02 I've in my /etc/sysctl.conf something like net.inet.tcp.log_in_vain=1 net.inet.udp.log_in_vain=1 The problem is this message appear event my rpcbind working (well appear in ps auxwww) and when sockstat -l tell me root rpcbind 932 6 udp6 *:111 *:* root rpcbind 932 7 udp6 *:1023 *:* root rpcbind 932 8 tcp6 *:111 *:* root rpcbind 932 9 udp4 *:111 *:* root rpcbind 932 10 udp4 *:734 *:* root rpcbind 932 11 tcp4 *:111 *:* Of course when this situation appear all my NFS client have big problem with any rpc calling (rpc.lock, remount nfs, etc...) How can the kernel tell this kind of message (what's I understand is the are a not welcome incomming connection) when the sockstat (and lsof) tell me the rpcbind listen is this port ? I've have restart rpcbind/nfsd/etc...nothing change. The server have all NIC in polling mode because without this flag the NIC disapear (em0 watchdog etc...) Today the only solution I've found is ... reboot the server :-( Any one have a explaination ? and solution....
