I've fixed up the problems I had with raid, and am now testing the
recent xattr changes with dbench and nbench.
The problem I've hit now is a severe memory leak. I have applied the
patch from Linus for the leak in free_pipe_info(), and still I'm
leaking memory at the rate of about 100Mbyte/minute.
I've tested with both 2.6.11-rc2 and with 2.6.11-rc1-mm2, both with
the pipe leak fix. The setup is:
- 4 way PIII with 4G ram
- qla2200 adapter with ibm fastt200 disk array
- running dbench -x and nbench on separate disks, in a loop
The oom killer kicks in after about 30 minutes. Naturally the oom
killer decided to kill my sshd, which was running vmstat :-)
Do you have today's memleak patch applied? (cut-n-paste below).
