i was told it is due to bug 407028 (even your error message is not same as in sol). rebooting unit is workaround.

Aiyappa_136133Hi Nitass,
I have tried rebooting the box as well but of no use event the error message also doesn't match so i dont think it is the known issue of 208 days. Is there anything i can check for

I have tried rebooting the box as well
if the warning message persists after rebooting, i think you may have to open a support case.

Which hardware platform is it and which version of BIG-IP are you running? Do you have a USB drive plugged in?

If it's the "208.5 days" issue, you might actually need to power-cycle the device instead of doing a software reboot.
