cisco 2900 router losing vlans

i have a cisco 2901 with c2900-universalk9-mz.SPA.151-4.M4.bin. I upgraded to this to solve an issue with any-connect not working with IE9 10 and 11. That is all OK now but I have a new issue in that the router is losing its vlan info and therefore all the nodes on them.

I get this error esw_mrvl_vlan_port_remove : Unable to find entry for VLAN(351) dbnum(7)

any ideas ?

Have you tried deleting the VLAN and re-create it?

How many VLANs are getting deleted or is it deleting all the VLANs?

1. Accroding to Cisco it is a known bug in 15.1(4)M3 but in this case, it doesn't look like it is.
    Can you do "sh ver" and verify?
2. vlan.dat file might be corrupted.  Backup vlan.dat file and recreate the vlans if possible.
3. Try upgrading the firmware to higher version such as 15.1(4)M4.1
