We have a Linux file server for a set of computer science and
engineering
labs where each lab contains machines running Mac OS X, Ubuntu Linux,
or some incarnation of Windows. At times the these machines become
almost unusable and I think I have narrowed the problem to smbd
processes
soaking up all the CPU on the server. Running 'top' on the server
reveals a dozen or so entries like the following:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
18229 millerbr 20 0 12420 3980 2992 R 26 0.1 0:03.85 smbd

18678 twharris 20 0 12780 4556 3552 S 1 0.1 0:11.35 smbd
...
Looking through the log files reveals nothing obvious at first glance,
but of course
I am not sure what to look for and there are a lot of log files.
What steps should I first take to debug the situation?
Thanks for any and all help.
