I would like to help, but I believe that I need more information in order to give you an accurate answer. Exactly which command are you using to shutdown the system? Can you send along a snippet of the last few lines of output on the terminal before it hangs? Does it always hang in the same place? With this type of information, I believe that the problem can be diagnosed. See ya later, Andy -- Andy Stewart Founder Worcester Linux Users' Group Worcester, MA, USA http://www.wlug.org

Question

by Pierce C. Barnard

Hi, I recently purchased SuSE V7.3 and when I shut it down, it hangs while shutting down all of the system processes. How can I fix this problem with the shut down proceedure?

Re: [Wlug] itch to scratch...

by Michael Frysinger

heh i encounter the same problem all the time i mount my mp3s via samba and then my windows box reboots. samba freaks the mount and processes get fucked in the ass. here is how i solve it ... drop all packets to your windows machine long enough to kill all the offending processes and umount the drive. iptables -I INPUT 1 -d WINDOWS -j DROP or if thats a prob (like you're ssh-ing from your windows machine :D), add in -p TCP --dport 139 -mike ----- Original Message ----- From: "Keller, Tim" <Tim.Keller(a)stratus.com> To: <wlug(a)wlug.org> Sent: Friday, March 08, 2002 09:38 Subject: [Wlug] itch to scratch... > I'd like to figure out a way to "assassinate" processes that get stuck in > the "waiting IO" state when I know there's no way they'll ever come out of > that state. > > I just had to reboot my linux workstation to resolve such an issue.

Chart generation tools

by John Stoffel

Guys, Does anyone have any recommendations for data plotting or charting tools under linux/solaris? I'm aware of gnuplot, xmgr (ACE/gr), grace (ACE/gr descendant) but none of them is really what I want. I'm trying to take a bunch of data from my backups and graph the output nicely. I'd like to have both: - stacked plots (show the totals, with breakdowns by groups). - pie charts for individual days - line charts for trend analysis And of course all of this should be easy to do from the Unix command line and/or control/data files. I currently have a script which uses gnuplot to graph the data, but it's not the nicest. I'm looking into using 'grace', but it's not well documented and it's really pushed more to scientific visualization. I'll try to put what I have up on the web at some point, so you can see what I'm trying to do... but if you've ever used Legato Networker, I've got a tool called 'nss' (http://jfs.ecotarium.org/sources/nss) which generates reports on backups.

RE: [Wlug] itch to scratch...

by Evans, Robert

Potential difficulties with this idea: - There may be insufficient information about state of the process for the kernel to free up some resources. It might require code in drivers to assist. - Locks or mutexes held by the process should not be freed unless the resource the lock is protecting is in a consistent state. This gets very application specific. Robert N.

I'd like to figure out a way to "assassinate" processes that get stuck in the "waiting IO" state when I know there's no way they'll ever come out of that state. I just had to reboot my linux workstation to resolve such an issue. I had an file system containing mp3's mounted via smbfs. Unknown to me, this connection had become stale, so when I started up xmms, it hung and immediately went into the dreaded "waiting IO" state, while holding onto my sound hardware. I did a df and had that stuck as well, along with the bash shell I spawned it from. I think I'd like to write a "SIGMURDER" signal that would tell the kernel to just through its tables and forcibly unallocate all the resources a particular process is holding, close all its handles, etc. So before I even contemplate this endeavor, is their away to already do this?
