I could kind of solve it by only enabling the following snmp sections

  • hr_cpu
  • hr_fs
  • hr_mem
  • hr_ps
  • if
  • if64
  • if64adm
  • ifoperstatus
  • snmp_extended_info
  • snmp_info
  • snmp_os
  • snmp_uptime
  • ucd_cpu_load
  • ucd_cpu_util
  • ucd_disk
  • ucd_diskio
  • ucd_mem
  • ucd_processes

I disabled all other sections.
