SNMP daemon got terminated due to de-referencing a NULL pointer. If any error is detected on a received SNMP message, then the corresponding error counter would be incrementing. Before doing that, there is a piece of code that would extract the user name form the message. In case of the no user name available and is NULL the code which extracts the username will de-reference to NULL (without checking if the username is present or not) and the daemon terminates.

Fix: DISRUPTIVE action is needed before the fix can be put in place, and plan a maintenance window accordingly ! The Active CP needs to be rebooted to bring the CP s back in sync. Upgrade to Fabric OS 8.1.0 Note there is a CVR available for Fabric OS 7.4.1d, if needed contact DELL EMC support for RPQ and CVR v7.4.1d_cvr_brcd_594259_02 Workaround: DISPRUPTIVE workaround. plan a maintenance window accordingly ! The Active CP needs to be rebooted to bring the CP s back in sync Brocade DEFECT000623500
