I come across the problem when i wanted show user statuses in a list in which i used latest record of radacct row for each user but it was showing u ser was offline even if it was online in real, and saw that an old record of the same user was being updated.

Yes, you are right, problem is with NAS.

I was wrong, it was for the same user. I just thought it maybe for different users as well.

Since i thought  there was no problem with the normal working of freeradius  i thought no need to send debug output.
