Hi hraja,

DB2 has a bulletin on this, which states that the problem is probably with a third party product.

Give that a quick look and see if anything in your situation is described there.

The error suggests that there is another process locking the files that are used for Logging.  This could occur when using
a) Virus Checking software - in which case you need to make sure the folder defined in LOGPATH is excluded from the RealTime virus checking process AND blocked from use from any other user other than the db2 instance/admin id
-OR-
b) Backup software where the software locks the file while it is taking a back up of the file.
