I have a zabbix server running  5.0.11 , it keeps running OOM frequently until it crashes.
Found the LLD manager is eating all of the memory

• 1. ps aux -sort=%mem | head -n 10*
     USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
     zabbix   36567  0.3 83.3 69847240 51381160 ?   S    Dec03  21:47 /usr/sbin/zabbix_server: lld manager #1 [processed 152 LLD rules, idle 4.989597sec during 5.001287 sec] **

• 1. free -h*
                   total        used        free      shared  buff/cache   available
     Mem:            58G         52G        2.4G        3.4G        4.1G        2.6G
     Swap:          4.0G        1.2G        2.8G

Attached Dump of smaps indicating Heap memory is not letting go of the memory it uses. Can you help with a solution here?
