### Instruction:
ISIS-4-BFD_DELETE_FAIL
### Response:
(Severity: 4), (Category: ROUTING), (Description: IS-IS failed to delete one or more sessions with the BFD server. The connection to the server will be reset in an attempt to recover from the error.), (Recommended Action: This failure may due to lack of resources. Reduce other system activity to ease memory demands. If conditions warrant, upgrade to a larger memory configuration. If the failure is not due to a lack of resources seek support. Copy the error message exactly as it appears on the console or in the system log, call your Cisco technical support representative and provide the representative with the gathered information.)
