kernel: Page has mapping still set - continues

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Been having this problem, and posted about it before.  Thinking it was a
memory issue, I've replaced all memory on the server.  However, the
problem has continued.

Server is a Proliant DL380 (8GB RAM, 2 Xeon CPU), running CentOS 3.6, all
patches up-to-date.  Kernel is 2.4.21-40.ELsmp (problem seems to have
first manifested on kernel 2.4.21-37.0.1.ELsmp).  Disk is CCISS hardware
RAID-5, straight partitioning (no LVM).

This server runs an Oracle 10g instance, async I/O enabled to a NetApp
filer where most data is stored.

Traceback of latest failure follows (two crashes this morning).  Anyone
read these things well enough to tell me if there's any insight in this? 
There are no nVidia drivers loaded, only stock kernel modules.

Thanks in advance for any insight.
