Environment
EXOS 22.3
Cause
The host mobility routes are not getting removed once the ARP ages out. When the same ARP is re-learnt, the internal data structure maintains duplicate entries.
The internal data structure of the VRRP process continuously grows due to these duplications/multication. Eventually when no additional resources are available to sustain the growth, the processes crashes.
Resolution
A workaround is currently not available, and in order to prevent the VRRP process from crashing, the process can be restarted 
# restart process vrrp 
This should be done in a window, as there should be a loss of connectivity while the process restarts 

The following CR has been created for this: 
CR# xos0072698 "VRRP crash is observed when host mobility is configured and new host routes are learnt continuously."
 
Target Release(s):    EXOS 22.6.1
