we have running version 2.5.116 on (MS SQL server 6.5, SP4) ,with no
headaches in general,
(except stop records only and manual calls update does not work , -i.delay-
problem )

however when I upgrade to 2.5.124, I start to get Bad user name errors

such a query appears, (username ='') for all users
insert radlogs (RadLogMsgID, LogDate, Username,Data) values
(54,getdate(),'',servername)

but in the parsing screen I see the names of users normally
anyone have any idea ?
