[horde] HORDE: SQL QUERY FAILED

[grupo correo]

Hi again.

I have seen in my horde.log too many entries with this text.

HORDE: SQL QUERY FAILED: SQLSTATE[23000]: Integrity constraint violation:
1062 Duplicate entry '{5423e876-9b2c-46c2-997b-184ac0a81b25}51' for key
'PRIMARY'  #012#011INSERT INTO horde_activesync_state (sync_key, sync_data,
sync_devid,#012#011  sync_mod, sync_folderid, sync_user, sync_pending,
sync_timestamp)#...

How can i avoid this issue in my system? is there any solution for this
problem?

Regards.
