Some time ago I discovered high load on my site server system caused by MySQL instance (about 50% of CPU time). I checked httpd load and found nothing serious (about 0.2 req/sec). Then I enabled query logging in MySQL and got lot of following lines:

...
1 Query       INSERT INTO 2frmdb_ses (ses_id, time_sec, sys_id, user_id) VALUES ('da44744b0744e7182e2d8e21bb2b4063', 1357649603, '', 2001593538)
1 Query       INSERT INTO 2frmdb_ses (ses_id, time_sec, sys_id, user_id) VALUES ('517bf2b9b646c2e48dbc28f996941b15', 1357649603, '', 2053834729)
1 Query       INSERT INTO 2frmdb_ses (ses_id, time_sec, sys_id, user_id) VALUES ('ecb78d35baa48deec43abf7d649ea7eb', 1357649603, '', 2055756004)
...

I checked users table against that IDs (user_id above) and found nothing - users table has no such IDs at all.

Is it normal? If no then how is that possible and what should I do to stop that?

Forum version 3.0.1, php version 5.3.17, MySQL version 5.0.84, server OS - Slackware Linux 13.0.
