what is attr#_148 in URS logs?

[URSMan]

Dear Genesys Engineers:

on our production site our URS is going berserk and shows a lot "emergency: invalid connid" errors.

What is even worse some of the attributes are shows as like this:

received from 69441(--)ctib:7840(fd=24) message EventAgentReserved
        AttributeCustomerID    'Resources'
        AttributeTimeinuSecs    143513
        AttributeTimeinSecs    1159751171 (10:06:11)
        AttributeReferenceID    24009
        AttributeThisDN '4512@Switch_S8720'
        AttributeAgentID        '7017'
        AttributePlace  'S8720_4512'
        AttributeTimeout        15000
        [color=Red]attr_#148      0000000000b5457[/color]



This sort of "attr_" appear all over the place. Why does is do it? What does it mean? And what can I do to stop it?

URS: 7.1.001.03
LDS: 7.1.000.03
T/S (Avaya): 7.0.206.01

Thanks alot!
