why acturally use these too much memory by asd process, is there memory leak happen ?

namespace dmp {
        replication-factor 1
        memory-size 60G
        default-ttl 15D # 30 days, use 0 to never expire/evict.
        high-water-memory-pct 40
        high-water-disk-pct 80
        storage-engine device {

        file /pdata1/aerospike.dat
        filesize 200G
        write-block-size 1M
        data-in-memory true

        }
}

According to Known Issues 4.5.2.1 does have a memory leak if you are using predicate filters on lists or maps:

  • [AER-6129] - (KVS) Predicate filter memory leak observed when using list/map iterate. Fixed in version 4.5.2.7.
