Unexpected connection error when host.get() with search

[jmao]

I have a python script to find out get all hosts managed under Zabbix.

method = 'host.get'
params = { "output" : "extend", }
params['search'] = { "host" : '*' }
params['searchWildcardsEnabled'] = 1
params['limit'] = 5000
error, response = request(method, params)
pprint.pprint(len(response['result'][0]))

Everything else works with the API but when I try to search all, I see zabbix returns 31 hosts and failed to connect again. Any suggestions or an easier way to get all hosts managed by Zabbix? Thank you.

31
