No, I don't think so. datasize was the parameter I was most suspecting; and it assumes that a particular process was causing the crash (which is unlikely; the OS is supposed to protect you against it). Most likely, the crash was not directly caused by a shortage of virtual memory. You would have to diagnose through crash dumps, but it could be that some more specific resource was exhausted. Or perhaps the memory leak left dangling references in a vnode. We also had a some what similar experience - swap partition was not being fully utilized (but no NFS in use). Found that the size of SWAPMETA limits the total usable swap space. This is more likely with a custom config and tweaked limits. vmstat -z | egrep LIMIT|SWAPMETA --- sriram OK, Thanks a lot for your explanations.

If this is the explanation of what happens, how can I tune this ? Should I use larger pages (superpages seems to be enable by default on FreeBSD9-amd64) ?

kinternet alternative in FreeBSD

Many years ago, FreeBSD 4 obsoleted Linux as my home desktop, and I do not regret the choice. Depending on what _you_ actually *do* with your computer, there _may_ be certain obstacles. For clarity, I do not need exactly kinternet, I want only an GUI frontend for pppdial which possibly resides in system tray and can be used to control network connections. As I said, I've heared of a tool named kppp, and according to the traditional naming convention in KDE (of _that_ time), I assume this is a KDE program for dealing with ppp. Even though networking is done at OS level which doesn't have such a tight integration with desktop environments as this is done in Linux (as the big three desktop environments are quite Linux-centric), ppp can be invoked by the user (if he has been granted the required permissions by the system administrator). If a KDE program can communicate with the ppp command line tool, it should work. In openSUSE kinternet is a frontend for smpppd package. smpppd requires ppp. I will try to look into it whether smpppd can work with FreeBSD's ppp. That sounds like an interesting approach. Good luck! I know that's basically possible. Many years ago, I wrote a Tcl/Tk-based frontend with buttons to enable / disable the connection, see the status and the elapsed time. If that has been possible, chances are good that KDE in its much advanced manner has something comparable. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

May I just say, that some years ago I did just as you are doing now and started to use FreeBSD 6.x in place of Linux. I was used to KDE3 and so naturally tried to get that up and running. Since then, my needs have changed and discovered it was so much better to do away with these GUI tools such as the one(s) you refer to. Working from the command line in FreeBSD is SO much better, more flexible and powerful, and so ditched KDE altogether and now use a simple tiling window manager. You really don't need KDE or Gnome, ... , you can benefit much more from a BSD UNIX system without that crap. It's your choice naturally but IMO you will have a much nicer experience without KDE. All of your networking needs can be achieved from the command line and you won't fill your system with thousands of libraries and other code that you simply just don't need. Of course I'm biased but my experience since I changed to FreeBSD will no doubt be similar to yours should you choose to stick with it so I hope my comments have been of some use. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

legal question on licence terms
Sirs, I'm looking at your licence terms and conditions and particularly the section on redistribution restriction on a number of ports. The restriction is stated as being applicable to redistribution on mass media. Could you please elaborate on what this means - clearly a number of leading solutions use FreeBSD so I'm trying to properly understand when and how the redistribution restrictions apply. In our own case we would be using FreeBSD as a component of managed services that we would be providing to our customers. The software would remain on our own server and would not be separately available to our customers. We assume therefore that this in any case does not constitute redistribution. Many thanks.

Minecraft sound (ALSA)
Hey guys!
I would like to play Minecraft on my FreeBSD box, so I installed
games/minecraft-client. It starts, but I do not have any sound. The
reason for that is that Minecraft uses ALSA and ALSA does not find any
soundcards:
Starting up SoundSystem...
Initializing LWJGL OpenAL
(The LWJGL binding of OpenAL. For more information, see
http://www.lwjgl.org)
AL lib: alsa.c:960: no playback cards found...
AL lib: alsa.c:1017: no capture cards found...
ALSA lib confmisc.c:768:(parse_card) cannot find card '0'
ALSA lib conf.c:4154:(_snd_config_evaluate) function
snd_func_card_driver returned error: No such file or directory
I am not sure what to do here and how to wrap my OSS system in an ALSA
system. I installed audio/alsa-lib, audio/alsa-plugins and
audio/alsa-utils. My asoundrc looks like this at the moment:
pcm.oss {
type oss
device /dev/dsp
}
However I cannot play any MP3s via aplay. Do you have any ideas?
