mounting failed can not allocate memory
« on: March 20, 2011, 03:46:56 AM »
For just about any extension I try to download from app-browser, I end up receiving a message at the end of the download like this  "mount: mounting /dev/loop148 on /tmp/tcloop.icu failed: can not allocate memory"

I'm not out of memory or swap. I have microcore 3.5.1

Xfce4 desktop and 25 extensions onboot.

246780 kb ram
8 mb video
784600 kb swap partition

I have no idea what this could be caused by but any help would be GREATLY appreciated.

I have the same problem sporadically
Seems to be a zlib problem (used by squashfs)

Issue the dmesg command in a console and look at the last lines.  Is there a zlib error message?

Retrying the mount sometimes works

Yeah your right.

It says SQUASHFS error: Failed to allocate Zlib workspace

and retrying the mount "on a very good day" works but that still sucks.......

Hopefully somebody can be a hero and help us out

I'll keep my eyes  open :o

is '/tmp/tcloop.icu' a typo or literally so?

Not sure what you are exactly doing but 149 extensions plus Xfce4 does sound a bit out of proportion with 256MB RAM.
Note that icu is a rather big extension (7.8MB squashed).

Please also check for free space in your filesystems (squashfs excluded) with 'df', particularly tmpfs.

Note that kernel memory can't be swapped. One may see this error while still having plenty swap.

Hey Tiny, you asked - "is '/tmp/tcloop.icu' a typo or literally so?" No it's NOT a typo but what the heck is icu ? I think I was trying to download and install Clementine at that time - what's icu mean?

Also what do you mean "149" extensions - I only have 25 onboot and 0 ondemand. Am I missing something?

tmpfs use is at 9 % mounted on /

tmpfs 0% mounted on /dev/shm

/dev/hda3 2% /mnt/hda3

/dev/hda3 2% /home

/dev/loop0 100% /tmp/tcloop/netfilter-2.

and everything below that is at 100% - I don't know if that's good or normal or what?

Then there seems to be something wrong with your dirname(s).
For icu.tcz extension see repo.
Looking at clementine.tcz, with 246780 kb ram I would not attempt to install a music player of 64MB...

The fact that you report /dev/loop148 failing to mount means either:
1:You use 149 extensions
2:You use loop devices partially for other purposes than extensions
3:You are leaking loop devices

Each onboot item could have a dependency chain of multiple extensions.

Your filesystem usage seems to be most moderate, so we can exclude issues there.

EDIT: Check your loop devices with
Code: [Select]
losetup

It would help to post `free` output and /proc/meminfo, to see how close we are.

 Here's what I got from losetup command ( I uninstalled audacity.tcz which was onboot and I also uninstalled about 50 extension that weren't being used and were just sitting in appsaudit under dependencies NOT being used.)

 I uninstalled them because I thought it might help and I wasn't using them anyways but NO LUCK - Same issue.

Forgot to say, also /proc/meminfo after executing "sudo cache-clear", for comparison. After you have seen the error, of course.

Okay I tried downloading Clementine.tcz again for this example and here's how it went.
mount: can't setup loop device: No space left on device

Then I did /proc/meminfo

OK, thanks. Weird, you have still plenty of ram free.

Well I just turned the computer on 10 minutes ago "as soon as I turned it on I came straight to the forums."

Where as last time I had it running all day. IDK if that matters. But either way the problem still is there. Do ya think I should just do a reinstall ?




EDIT :  Also if I choose to do a complete reinstall of MC is there a better way to wipe the entire computer completely clean "100%" or does cfdisk do that "100%" just by deleting the partitions?

Thanks, George

AFAIK the 'fdisk' and 'cfdisk' tools are only working on the partition table (e.g. in the MBR) but do not format or wipe the device.

I personally have done something like sudo dd if=/dev/zero of=/dev/hda bs=2M as a "poor man's wipe". Of course one could use the 'wipe.tcz' extension instead, but I'm happy to use what is available in Core as in my case speed of execution is more important than security. Just be sure with the device name (e.g. '/dev/hda') you specify. Any typo on such a command can be very "painful" as you could destroy the content of a unintended device.

BTW, I believe that the typical 'mkfs.*' command also formats to content of the partition. But if you want to be 100% certain I don't see any harm in using a "wipe; fdisk; mkfs.*" sequence.

sudo dd if=/dev/zero of=/dev/hda bs=2M
