Hi, I'm running Samba 3.0 on a Solaris 9 server. If you look at the output of top you'll see that that nmbd process is killing this machine: I've restarted Samba numerous times, and each time the load goes down immediately and when I restart it the load goes up and nmbd starts to take up all the processor time. load averages: 21.18, 19.61, 24.65 11:04:20 210 processes: 187 sleeping, 22 running, 1 on cpu CPU states: 0.0% idle, 2.4% user, 97.6% kernel, 0.0% iowait, 0.0% swap Memory: 512M real, 106M free, 329M swap in use, 2005M swap free PID USERNAME THR PRI NICE SIZE RES STATE TIME CPU COMMAND 25060 root 1 46 0 3296K 1504K run 0:37 4.75% nmbd 24844 root 1 45 0 3296K 1496K run 1:35 4.70% nmbd 24965 root 1 46 0 3296K 1544K run 0:58 4.66% nmbd 25029 root 1 45 0 3296K 1496K run 0:41 4.64% nmbd 25040 root 1 38 0 3296K 1496K run 0:39 4.63% nmbd 24902 root 1 46 0 3296K 1496K run 1:09 4.59% nmbd 24779 root 1 48 0 3296K 1496K run 2:25 4.58% nmbd 24833 root 1 47 0 3296K 1544K run 1:39 4.56% nmbd 24786 root 1 48 0 3296K 1496K run 2:15 4.55% nmbd 24923 root 1 45 0 3296K 1544K run 1:02 4.55% nmbd 25134 root 1 48 0 3296K 1496K run 0:20 4.55% nmbd 24910 root 1 48 0 3296K 1488K run 1:05 4.53% nmbd 25101 root 1 48 0 3296K 1504K run 0:24 4.53% nmbd 24952 root 1 48 0 3296K 1552K run 1:01 4.52% nmbd 25209 root 1 48 0 3296K 1504K run 0:06 4.52% nmbd My initial thoughts was a virus is causing an unusual amount of NetBIOS traffic so I've got a Virus scan going at the moment. Has anyone seen this problem before?? Is there potentially a problem with samba 3.0 that I'm not aware?
