Do you have any debug events related to OIDs ? Also check zenperfsnmp logs for warnings or errors.
I had this kind of problem with some old Cisco switches and in my case it was related to snmp agent in the device. Possible ways to remedy this would be to use snmp v1 if your device has only 100Mbps interfaces and reduce the number of OIDs fetched per request (zMaxOIDPerRequest in configuration properties).
