Error description

• ITNM 3.8 FP5 with IF001 installed on
  RH Linux 5
  
  Customer can unmanage a chassis from the gui (hopview) and can
  still see polling traffic going to that entity.  It appears to
  only be snmp poll traffic because the tcpdump shows ICMP echos
  stop when unmanaeged.
  
  Steps to recreate:
  
  1)Create domain and populate with entities
  2)Create poll policies for Chassis Ping, Interface Ping, and
  several snmp related polls
  3)After confirmation that these devices are being polled,
  unmanage a device (chassis) by right click and choose "unmanage"
  from the gui.
  4)Observe that all the logging indicates the device has
  been removed from polling.
  5)Use tcpdump or similar to monitor port traffic and find that
  this is truly not the case and that there is still some polling
  of the device.  It appears that ping traffic has stopped but we
  are still seeing snmp polling continue.
  

Local fix

• Restart the ncp_poller process after unmanaging the device.
  This is not an acceptable workaround in some cases.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED:                                              *
  * Users of network polling, also using manage/unmanage         *
  * functionality in the GUI                                     *
  ****************************************************************
  * PROBLEM DESCRIPTION:                                         *
  * A node is unmanaged in the GUI using the right-click menu:   *
  * it continues to be polled by active policies.                *
  ****************************************************************
  * RECOMMENDATION:                                              *
  * This fix will be included in | fix pack |                    *
  * 3.8.0-ITNMIP-FP0007 and | fix pack | 3.9.0-ITNMIP-FP0001     *
  ****************************************************************
  The problem actually only occurs when more than one policy is
  active (which is usually the case).  Only the first active
  policy responds to the changes in managed status.  The problem
  also occurs for interface polls when individual interfaces are
  managed or unmanaged.
  

Problem conclusion

• | fix pack | 3.8.0-ITNMIP-FP0007 and | fix pack |
  3.9.0-ITNMIP-FP0001
  

Temporary fix

• restart ncp_poller process.
