Hi,

I can confirm that there still seems to be really a problem (hostap CVS 
20041206):

Tue Dec  7 15:45:36 2004
        Acct-Session-Id = "41B4DC04-00000007"
        Acct-Status-Type = Stop
        Calling-Station-Id = "00-02-DD-34-65-xx"
        Acct-Session-Time = 12167
        Acct-Input-Octets = 2516871
        Acct-Output-Octets = 13880197

Tue Dec  7 15:45:45 2004
        Acct-Session-Id = "41B4DC04-0000000A"
        Acct-Status-Type = Start
        Calling-Station-Id = "00-02-DD-34-65-xx"

Tue Dec  7 15:50:46 2004
        Acct-Session-Id = "41B4DC04-0000000A"
        Acct-Status-Type = Alive
        Calling-Station-Id = "00-02-DD-34-65-xx"
        Acct-Input-Octets = 2529142
        Acct-Output-Octets = 13883212

Tue Dec  7 15:55:47 2004
        Acct-Session-Id = "41B4DC04-0000000A"
        Acct-Status-Type = Alive
        Calling-Station-Id = "00-02-DD-34-65-xx"
        Acct-Input-Octets = 2530162
        Acct-Output-Octets = 13883878

The old Acct-Data plus the new one's are written to the new session records.

Matt.
