Why application/oracle database are not running properly on RHEL 5.9 kernel ?

Issue

• Getting below error while going to start the application / database:

netaapp85 : service redwood start
[root@netaapp85 ~]# service redwood start
Starting Redwood...
Starting SYSJCS.NETAAPP85 on netaapp85

• When running the same database on a server using kernel-2.6.348.1.1.el5 (or kernel-2.6.348.2.1.el5) causes these "your license is not valid" messages.
• When booting the system with previous kernel-2.6.18-308.11.1.el5, everything starts working again.
