3ND crashes during discovery, "exception caught"

[Rob_Korn]

During scan of existing mapped network, only 70

addresses in the range, my 3ND pops up error at the

"Generating Reports" step.



Here is some of the message:

"{Exception caught by Thread named "Server Cmd Queue" -

java.lang.NullPointerException



at

com.coms.wsd.tns.server.tools.merge.MGDiscovery.mergeMa

nagedNodeToUnmanagedNodesMap(MGDiscovery.java:1182)



(and several more lines like above)"



It will not close normally and I have to "end process"

to do anything. This is only happening on one segment

of the Map (but I fear the other 45 segments/sites will

start failing now).



HELP from anyone is appreciated!

 Here is the update:

Only crashes if the scan hits a 7760 access point configured as a workgroup bridge on my WX2200 Wireless Mobility Domain.

The only way around this was to skip the address of the above mentioned device.  My belief is that this setup, AP - Bridge, is confusing the software.
