Network Advisor - E-mail notification null

[Anonymous]

Hi,

We have the sotware Network Advisor ver 11.0.1 with the e-mail notification activated, and sometimes it sends messages like these:

Network Advisor  E-mail Report - Management Server Event

Network Advisor Build: 45

Network Advisor Server Address: x.x.x.x

Date: Fri Jul 22 04:31:09 EDT 2011

there are events "nulls" and I don't know what is the problem.

Thanks,
