Freeradius dies with Postgresql error

[Vegard Svanberg]

I'm using Freeradius with a Postgresql backend. Every two or three days,
Freeradius dies. These are the last lines from the log file:

Tue Feb 24 21:15:31 2009 : Auth: Login OK: [XXXX] (from client YYYY port 3 cli ZZZZZZZZ)
Tue Feb 24 21:16:34 2009 : Auth: Login OK: [XXXX] (from client YYYY port 3 cli ZZZZZZZZ)
Tue Feb 24 21:16:48 2009 : Auth: Login OK: [XXXX] (from client YYYY port 4 cli ZZZZZZZZ)
Tue Feb 24 21:18:32 2009 : Error: rlm_sql_postgresql: PostgreSQL Query failed Error: 
Tue Feb 24 21:18:32 2009 : Auth: Invalid user: [XXXX] (from client YYYY port 1509942 cli XX:XX:XX:XX:XX:XX)

Then nothing (it's gone and has to be started up again).

The problem is that this never happens if I run radiusd with -X, so I'm
having trouble catching more info. 

Any clues? This is Freeradius 2.1.0 btw. I've just upgraded to 2.1.3 to
see if the problem goes away.
