Hello, guys
I am having a problem with the processes smbd and nmbd. When nmbd starts on our sun, running solaris 2.7 and samba 1.9, it goes into a extremely high CPU utilization (over 99%).
Our smb.conf has been untouched for 8 years,so far, and I don't think this is a problem with it.
Running "gdb nmbd 2830 gave me:"
"/usr2/local/bin/gdb attach 2830

Can someone, please, point me to a good way of troubleshoot this problem.
Any help will be greatly appreciated, once our client has 6 machines with this problem and all its data needs to be available by samba.
Thanks,
Reinaldo
