Hi there, i am having a problem with a CSS 11501 machine. Problem started with a faulty compact flash slot0 that was replaced with the compact flash in slot1. since i had the configuration backed up i restored it to the new compact flash and also updated the ios version to 08.20.1.01(same with the original configuration). Also i have imported the certificates and everything works fine for a long period (1-3 Hours)i test this also by rebooting the machine. Then i reboot the machine one more time randomly and the CSS loads up with no configuration. when i do show run its blank and also show startup is blank. The certificates are all there. if i load the configuration again it will stay operational for 1-3 hours and then if i reboot it the configuaration will be lost again. Have you ever came across this problem, i need a fast resolution to the problem. i would apreciate any comment on this.
