A Cisco 6509 dropping SVI interafces configs

I've ran into a problem where SVI interfaces are being dropped within the cisco IOS config.

Cisco IOS Software, s2t54 Software (s2t54-ADVENTERPRISEK9_NPE-M), Version 15.1(2)SY2, RELEASE SOFTWARE (fc3)

This problem has happen dozen + of times. We are still investigating why? And how come  after the initial configuration, we can validate the cfg after initial config?

But later on the nvram startup-config will drop certain  SVIs from the startup-config. So upon a power cycle, you will come up with missing  configurations.
