When running top interactively, I can see various word in the state column :

nanslp, biord, select, uwait, lockf, pause, kqread, piperd, sbwait ...

Some like nanslp or kqread are self explanatory, others are not.

Tried man pages :

STATE is the current state (one of "START", "RUN" (shown as "CPUn" on SMP systems), "SLEEP", "STOP", "ZOMB", "WAIT", "LOCK" or the event on which the process waits), C is the processor number on which the process is executing (visible only on SMP systems)

Tried search engines :

Where may I get a complete list of possible process state under FreeBSD 9, and their meanings?
