IMP database error

[David Jorm]

Hi all,
I've installed IMP on several boxes and they've all gone fine. Following
the same procedure on another machine, I get the error:

Database error: Invalid SQL: insert into active_sessions ( sid, name,
val, changed ) values ('0d2754fdd29b2a557e9ba8f964ee58df',
'HordeSession',
'base64:JHRoaXMtPmluID0gJyc7ICR0aGlzLT5wdCA9IGFycmF5KCk7IA==',
'20010702173553')
MySQL Error: 1062 (Duplicate entry
'HordeSession-0d2754fdd29b2a557e9ba8f964ee58df' for key 1)
Session halted.

mysql -V
/usr/local/plesk/mysql/bin/mysql  Ver 11.12 Distrib 3.23.32, for
pc-linux-gnu (i686)

uname -a
Linux www 2.4.2 #1 Tue Mar 20 13:09:06 EST 2001 i686 unknown

Any ideas?

Thanks,
