fpc NH_FIND_FAIL_FOR_DELETION: NH: Failed to find nh (12928) for deletion

• This issue is due to high amount of routes received and next-hop id cannot get installed on PFE.
• After the NH computations fails and the memory is exhausted, the FPC might crash.
• Recommendation is to restart the FPC during the maintenance time. 
• Rebooting the FPC, will help in allocating the memory in a contiguous way, utilizing all of the memory blocks that are unused but cant be used as they may be small chunk scattered in between the allocated memory chunks.

If the issue still there after the reboot, please reach out to Jtac for further assistances
