file lock

I have an Essbase installation on Solaris 10 and need to get the backups configured. Unfortunately several key files are locked and Essbase (OLAP application) is not releasing the locks when the Essbase or the applications within stop running. It appears I can use chmod to unlock the files but I am concerned that the files will get corrupted and/or the apps will no longer run correctly. Any suggestions or advice?

Thanks.
