Faulty Interface Charts/Gaps (only Interface octets - In and Out ) [version 3.4.7]

[simao]

Good afternoon.
I have a problem that only occurs for data collected via SNMP from network interfaces.
I changed Timeout values, changed counters from 32 to 64, and nothing worked.

Examples:

Any help is appreciated.

Do you monitor busy Zabbix poller processes? What's in the queue?

Nothing in queue. I just have about 100 hosts with few items and triggers.
I suspected that could be pikes with this particular host, but every interface happens this gap.
gap.
Thanks.
