Low Memory Message! - Debian On C3000

[ArchiMark]

Hi,

On the whole, got X/Qt/Debian running OK on my lil' C3000....

However, lately, often when doing 'apt-get upgrade' I get a 'Low Memory' warning message window that pops up on the Qtopia side of the Z. Gives me a button that says 'Reboot'....at that point X/Qt/Debian has quit....

I recently reinstalled X/Qt/Debian on my Z to the internal microdrive...

Any suggestions to avoid this problem??

Thanks for any help.

Maybe some more detailed info will help someone to advise, please....

In Qtopia System Info app, here's what I see:

Also, just did 'df' in QKonsole and got the following:

Also, using Cacko b1.23 ROM with Tetsu 18a kernel....

Would greatly appreciate any input on how to deal with the low memory warnings... if need other info, let me know...

Thanks for any help!

have you tried adding quite a large swap file? I had this setup running up until yesterday, made a 650mb debian loopback partition and a 200mb swap and it was fine. had to do a factory reset yesterday because i broke something when installing new tetsu kernel, not related to debian.

Thanks for your input, daemon1!

Yes, I added a swapfile as per Meanie's install instructions on his webpage...don't remember off the top of my head the size of it...

Thought I'd clarify a bit on my previous post....

FWIW, I installed X/Qt/Debian this last time per Meanie's webpage.

I installed Debian to hdd3 using a loopback (instead of SD card) as he described.

I created a loopback filesystem on /hdd3 with 1024MB. He suggested either 256MB or 512MB if you wanted to install OpenOffice. So I thought what the heck, make it 1024...  

Was that a mistake to make it so big?

Also, I did setup a 128MB swapfile per his instructions on /hdd3.

HTH,

Mark

Hey guys, it pretty lonely here all by myself...

Really would appreciate some more input from some of the gang here...

Well, maybe I've figured what the *%$# is going on...  

Here's what I got....

[CODE]
#cat /proc/meminfo
                        total:      used:            free:    shared:      buffers:     cached:
Mem:         63524864      60510208    3014656         0      4165632   25546752
Swap:                    0                  0               0    
MemTotal:                        62036kB
MemFree:                           2944kB
MemShared:                            0kB
Buffers:                              4068kB

SwapCached:      0kB

HighTotal:                                0kB
HighFree:                                 0kB
LowTotal:                          62036kB
LowFree:                             2944kB
SwapTotal:                               0kB
SwapFree:                                0kB

So it looks like even though I thought I had setup swap space correctly, it seems that I have zero (0) right??

Thanks,

yeah, swap is not enabled.
to be certain, do a cat /proc/swaps as well, but it looks like its not enabled.
swap needs to be re-enabled each time you reboot.
where did you put your swapfile?

[ArchiMark]

Thanks for your help, Meanie!

You are right as usual...checked this last night and redid swap and voila!

It works well now....

Forgot that you had to re-enable each time you boot!

Well, live and learn....

Are you using my startx-wrapper script (ie xlauncher) because it tries to enable the swapfile if it is /hdd3/swapfile and it has the priviledge to do so (sudo for swapon is enabled or run as root)
of course you can change the script to tell it to look for the swapfile somewhere else as well

[ArchiMark]

Meanie, I am using your 'xqt-debian scripts'.

Is this the same thing?

Does this mean that I don't have to re-enable swap each time I reboot if I'm using your script??

Thanks,

yes, xlauncher (startx-wrapper mods) is part of the xqt-debian-scripts package.

if you start debian by running
# xlauncher debian
or tap on the debian icon on qtopia it should enable the swapfile automatically for you provided it has the right filename and is in the right place (or you edit the file and give it the right info ie modify the line SWAPFILE=/hdd3/swapfile) and sudo has been configured to allow zaurus user to execute /sbin/swapon

[ArchiMark]

Thanks for clarifying, Meanie!

Usually, I start by tapping on the Debian icon and I think I've set it up OK (per your excellent webpage!), so sounds like I should be OK, but will check it.

Thanks,

Mark
