Hi all.
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.
Active / Total Objects (% used) : 1548119 / 1609222 (96.2%)

I can find the same problem on ext3 fs.
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.
PS. Please Cc: me. I'm not on the list.
