After upgrading Junos, the syslog message, 'jnh_init_cassis_mem' and 'cassis_index_alloc_pool_create' is seen repeatedly and frequently. These messages are benign and can be safely ignored.
'jnh_init_cassis_mem'
'cassis_index_alloc_pool_create'
After upgrading (for example, from 17.4 to 18.4R1) the following messages may be seen repeating frequently:
