it's on 1.2.3

We are not moving to a 2.0 beta version as this server is in production.

'Normal' content is
$ cat /var/db/captiveportal.db
1281899223,10004,192.168.2.160,00:26:08:yy:xx:ii,105,405ce45ef655491c,,,,

(just an example of my captiveportal.db file right now)

Looks like the time stamp, IP, index and USER ID are missing.

Strange.

Some how, the database $cpdb (list with all the connected clients) fails to write correctly to your disk.
Destroyed in memory ?

On what are you running pfSense ?

I would re-install from scratch.

It happen in a random number of users. Sometimes happen in 40+ users, sometimes it happen in 300+ users. But I do not sure when it happen since I refresh the Portal page once a while.

Not a common issue, we support loads of CP environments and never seen that. The back end handling of CP is much improved in 2.0, and it's throughly tested and used in numerous serious production environments (ISPs and others). You may want to try it and see if that changes anything. Somehow it's missing some data on the back end in rare circumstances, and that may well be fixed.
