SubjectRe: Out of memory on 3.5 kernels
Good morning,

update: this problem still exists on 3.6.2-1-ARCH and it got worse:

I reformatted the external disk to use xfs, but as the my
root filesystem is still jfs, it still appears:

Active / Total Objects (% used) : 642732 / 692268 (92.8%)
Active / Total Slabs (% used) : 24801 / 24801 (100.0%)
Active / Total Caches (% used) : 79 / 111 (71.2%)
Active / Total Size (% used) : 603522.30K / 622612.05K (96.9%)
Minimum / Average / Maximum Object : 0.01K / 0.90K / 15.25K

I am wondering if anyone is feeling responsible for this bug or if the mid-term
solution is to move away from jfs?

Cheers,

Nico
