snmpd發生問題

yuwen

OS為Debian, 跑snmpd 5.3.0.1 + mrtg不到10分鐘 snmpd就會自己發生錯誤, error message如下:
error finding row index in _ifXTable_container_row_restore
error finding row index in _ifXTable_container_row_restore
error finding row index in _ifXTable_container_row_restore
error finding row index in _ifXTable_container_row_restore

  It's unlikely this agent can serve any useful purpose in this state.
  Run "snmpconf -g basic_setup" to help you configure the snmpd.conf file for this agent.
Error opening specified endpoint "udp:161"
Server Exiting with code 1

我的snmpd.conf(只列出我修改過的):
com2sec readonly  default          public
rocommunity  public

可以請教有哪位大俠能幫幫我嗎? 謝謝.
