while searching for 'freebsd process states' on google i came across this thread: http://lists.freebsd.org/pipermail/freebsd-questions/2006-December/138024.html i'm a new subscriber, so i can't reply to the original thread. i'm guessing fr0zen@sbcglobal.net's original question was something more like: "that do the values in the STATE column in top mean?" here's an example of what i'm talking about: ## bad 'top' formatting to come PID USERNAME PRI NICE SIZE RES STATE C TIME WCPU CPU COMMAND 95698 mysql 20 0 388M 349M kserel 0 266.7H 0.63% 0.63% mysqld 98237 jffnms 8 0 21224K 14412K nanslp 0 0:02 0.59% 0.59% php 98239 jffnms 96 0 22124K 15292K select 1 0:02 0.49% 0.49% php 98596 root 96 0 4124K 2560K CPU1 1 0:00 0.51% 0.05% top 1263 root 4 0 1408K 708K accept 0 0:07 0.00% 0.00% vsftpd 3405 galbrecht 8 0 4876K 2676K wait 0 0:00 0.00% 0.00% bash 94414 root 4 0 3284K 1968K sbwait 1 0:00 0.00% 0.00% mysql ## end of bad formatting this snippet of top shows the following values for STATE: kserel, nanslp, select, CPU1, accept, wait, sbwait this thread has already cleared up these states: nanslp: "Waiting for < 1 second." -grog@freebsd.org select: "Waiting for a select() to complete" -grog@freebsd.org wait: "Waiting for something to happen, possibly time limited (>= 1 second)" -grog@fbsd top(1) tells us: "STATE is the current state (one of "sleep", "WAIT", "run", "idl", "zomb", or "stop")" eh, not so much. man clears up some of these states: sleep: "The sleep command suspends execution for a minimum of seconds." - sleep(1) accept: "accept a connection on a socket" - accept(2) i bet i can answer with: run: process is running? zomb: zombie process, terminated but not removed from memory that leaves us with: kserel? sbwait? idl? stop? does the previous answer still apply ("ask the developers of those programs")? -g -- Greg Albrecht (gregoryba@gmail.com) An Indie, Hip Hop and IDM Podcast: The Letter G http://theletterg.org
