1) Do you use 32-bit or 64-bit counters for SNMP?
FAQ from Cisco
2) Check your Timeout= settings in zabbix_server.conf. Increase it up to 30 seconds.
3) Check if you can remove "Use Bulk Requests" check (for zabbix version 2.4+), because some network devices cannot properly response to bulk SNMP request.
