vmunix: mlock_region failed.

[Jdamian]

Hi guys.

Two moths ago I configured my system (kernel parameters, driver asyncdsk, /dev/async, /etc/privgroup, ...) to allow Oracle DB to access raw disks in Asynchronus mode.

Now I found the following message in syslog.log:

Jan 15 11:12:16 preprod vmunix: mlock_region failed..
Jan 15 11:15:37 preprod above message repeats 40 times

This message appears since the day I reconfigured my system.

What is the problem ?

HI J.

I found this post:

It refers to a change in the oracle buffer pools.
