Swapoff -a : cannot allocate memory

Poison Nuke · 08-09-2012, 10:02 PM

Hello,

suspicious problem.
I try to unmount swap i order to change partitions, but that is not possible, the error from above is shown.

Code:

~> swapoff -a
swapoff: /dev/sdb2: cannot allocate memory
swapoff: /dev/sda2: cannot allocate memory

But there is plenty of free memory

Code:

~> free -m
             total       used       free     shared    buffers     cached
Mem:          8077       2829       5247          0        796       1166
-/+ buffers/cache:        866       7210
Swap:         8205          0       8205

that is the frist time I encountered this problem and I have some similar configured systems, where all is ok.

Any ideas?

Showing /proc/meminfo is more useful. At any rate it's possible you'll find a solution in that linked thread.
