db2ckpwd not running under root

[db2dude]

We have a small problem in one of our database hosts in which the
db2ckpwd daemon process runs under the instance owner id instead of
"root".

Due to this, no other id except the instance owner is able to start
the database instance.

I see the following error messages in the diag if a 'db2start' is
attempted by any other id:

This is running on DB2 9.5 FP1 on AIX 5.3.

Any help would be great!

Thanks,

P.S: - The instance owner home directory is NOT mounted using 'nosuid'
since most of the online solutions pointed to that.

Who installed DB2? Was it installed as root, or as db2ts? If root, does a
db2iupdt fix it? If db2ts, have you run the script that enables root
functions (db2rfe)?

DB2 was installed as root.

This instance was migrated from DB2 V8 FP14 to DB2 V9.5 FP1 and so
db2imigr was run as root.
