I have trouble with latest stable kernel (2.6.13.4). I set up samba server on reiserfs and begin to copy a huge number of file. After one day, the system is very slow and almost not usable. The slabtop output is here.

The FC3 latest kernel(2.6.12-1.1378_FC3smp) also. It seems no difference between UP and SMP. The problem is not solved even if I stop and restart the samba server. Please give me your help. Thanks.
