Broken pipe error when my LLD data size is huge (ie more than 10000)

[naveen.s]

I am updating LLD using zabbix agent which uses custom parameters as shown below

UserParameter = sfa.get_ctrl, python /home/naveen/zabbix/sim/get_controllers.py

where python /home/naveen/zabbix/sim/get_controllers.py return the following data

{
  "data": [
    {
      "{#TITLE}": "Controller 1",
      "{#HEALTHSTATE}": "HEALTH_OK",
      "{#STATE}": "OK",
      "{#PRIMARY}": "Yes",
      "{#ID}": "id-ctrl-1",
      "{#LOCAL}": "Yes",
      "{#DESCRIPTION}": "Controller"
    },
    {
      "{#TITLE}": "Controller 2",
      "{#HEALTHSTATE}": "HEALTH_OK",
      "{#STATE}": "OK",
      "{#PRIMARY}": "Yes",
      "{#ID}": "id-ctrl-2",
      "{#LOCAL}": "Yes",
      "{#DESCRIPTION}": "Controller"
    }
  ]
}

But if my scale my no of items from 2 to 5000 my json data will get large and i am getting broken pip error like below.... is there any other proper way to to feed input for UserParameter ???
