Yeah, but what does it mean? [Was: Re: File trees: the deeper, the weirder]
This has bugged me for a long time and I guess my morning coffee hasn't kicked enough for me to let it go today. It's not documented anywhere that I can find and that includes a grep of all src and man pages. Google and Ask just give the What is vnlru? page in a handful of languages, a whole bunch of calcru errors and various chatter about vnode-related system slowness. It's not even in a comment in vfs_subr.c! What does vnlru stand for? VNode List Recycling Unit? Someone please tell me.

According to the ps(1) manual page, the 'Z' flag means that the process is what is commonly known as 'zombie' - a process that has ended its execution, either exiting voluntarily or killed by a signal, and is being kept in memory until its parent process collects whatever information is necessary. The fact that you are seeing those zombie processes may mean one of two things: either the 'sh' processes have ended really, really recently and their parent has not yet had a chance to invoke one of the functions described in the wait(2) manual page to collect the information, or the 'sh' processes have terminated some time ago but their parent is busy doing something else, possibly locked up or something. You may gather a lot more information by including the parent process ID in the 'ps' output: try 'ps axl' or 'ps axlwww', see what has invoked all those 'sh' processes, see if it has left any logs as to why, what happened, and so on.
