comment Maximum number of users logged simultaneously into Linux
@OsamaHussain: /etc/ssh/ssh_config is the config file for the ssh client. If you install the "openssh-server" package you get the server, including the /etc/ssh/sshd_config file.

comment High system cpu load (%sys), system locks
Ah, you can check e.g. /proc/softirq; unfortunately I don't know of any tool that displays individual softirqs over time. Alternatively, run something like "dstat -ar --socket --tcp" when you get a spike and post the results.

comment High system cpu load (%sys), system locks
That %si corresponds to time spent in softirq handlers? Well, if you don't believe me or some other documentation you might find, you can read the kernel source code.

comment What exactly is a “load” when referring to node status of a Compute Cluster?
@JacobHayden: Sorry, to clarify, the number of running and runnable THREADS, not processes. I don't know what you mean by the size of the processes; if you mean memory usage, then no, it doesn't affect the load average.

comment What exactly is a “load” when referring to node status of a Compute Cluster?
@JacobHayden: The number of running and runnable processes averaged over some period of time, typically, 1, 5, 15 minutes.

comment Best practices for mounting Sun SAN NFS on Linux (Debian Squeeze)
FWIW, Linux no longer supports the intr option. From nfs(5): "The intr / nointr mount option is deprecated after kernel 2.6.25. Only SIGKILL can interrupt a pending NFS operation on these kernels and if specified, this mount option is ignored to provide backwards compatibility with older kernels."
