2948G L3 IOS version

[tuks]

Im employing the above switch model to do my core routing and switching. This include acoule of fastetherchannel and two BVI's. I recently encouter problems with one BVI. It went doen and will shut down all the connected device in that BVI. However, from anpther BVI I can ping servers and routers on the other BVI.

Could this be a problem with the IOS version Im using ?
Here my IOS Version:
