Do you have any Nexus switches in your environment?

Dear Wesley Austin,

yes our network we use nexux5k & nexus2k switches ...

can you explain me how to affect nexus in this problem ..?

Workaround:
1. use VTP version 2.
2. do one of the followings:
a. Configure the N7K as a VTP server and the IOS devices as VTP client
or
b. Configure the N7K as VTP client and other IOS devices as VTP server.

Once the VTP database on the IOS is corrupted, the only way to recover from the error condition is to clean up the VTP database.

For CAT4500, the procedure is to enter command "erase cat4000_flash:" and relaod.
For CAT2900, 3560, 3750, the procedure is first backup the configuration, write erase, delete flash:vlan.dat, and then reload. After the switch boots up, restore the configuration.
