Hi,
I see some strange behavior on a SLES9 client v 1.3.2 running on
power5. After some time the system log (dmesg) is full of messages like
the following:
Badness in page_remove_rmap at mm/objrmap.c:383
Call Trace:
[c000000072227950] [c0000000000b1a70] .unmap_vmas+0x67c/0x914

LR = 0xff5664c
The system show very poor PVFS2 performance and pvfs2-client-core takes
a lot of cycles. The file system is under moderate load at this time. I
don't know if the dmesg is a cause or the result of pvfs2 degradation.
Has anybody seen such a behavior?
Thanks,
--andrew
