I have a machine with 4GB, running 64bit 2.6.37, xfs on top of soft raid5.

Recently after using xfs_fsr (and getting a oops) had to do xfs_repair and now 
I'm no longer able to mount this filesystem with usrquota and grpquota.

xfs eats all ram, from slabtop:
3756380 3756380 100%    1.00K 244655       16   3914480K xfs_inode
251712 251711  99%    0.06K   3933       64     15732K kmalloc-64
118482 114287  96%    0.55K   4233       28     67728K radix_tree_node
 88768  88711  99%    0.12K   2774       32     11096K kmalloc-128
 28713  28713 100%    0.08K    563       51      2252K sysfs_dir_cache
 22974  22973  99%    0.09K    547       42      2188K kmalloc-96
  9776   9776 100%    0.25K    611       16      2444K kmalloc-256
  7791   7791 100%    0.19K    371       21      1484K kmalloc-192
  7168   7097  99%    0.01K     14      512        56K kmalloc-8

machine is not responsible anymore, xfs ate all ram

If I don't use usr/grp quota then filesystem mounts without a problem.

What are my options now? I need this system running again with quota but 
loosing all quota information is not a problem (I can set it again).
