[TuxOnIce-users] Help with "Not enough free memory" error

[Ben Rich]

Hi,

I've used TuxOnIce before, and I has always worked well for me.  Now,
I have a problem with it, and I'm hoping that someone will be able to
help me out because I think it must be a simple problem.  When I
initiate hibernation (sudo hibernate -F /etc/hibernate/tuxonice.conf),
the system begins to hibernate but then wakes up again right away.  In
dmesg output, I see the following:

PM: Creating hibernation image:
PM: Need to copy 1032191 pages
PM: Normal pages needed: 1032191 + 1024, available pages: 931534
PM: Not enough free memory
Error -12 hibernating


I'm trying to save the image to my swap partition /dev/sda2 which is
4GB (same as RAM).  Here is the output of the free command, which
shows that very little memory is actually being used, and that the
swap partition should be big enough to hold the image:

[ben at t400s ~]$ free -m
            total       used       free     shared    buffers     cached
Mem:          3858        645       3213          0         17        297
-/+ buffers/cache:        329       3528
Swap:         4096          1       4095


Please ask if there is any more information that I can provide that
will be useful for debugging this problem.  Thank you in advance.
