I got a multi-page form with quite a few components and I have a few hundred submissions by users who are allowed to submit only one entry of this form.

On few users (10-15 out of a few hundreds total) I get the following error in the log:
"Duplicate entry XXX for key X query: INSERT INTO webform_submitted_data"

This is from the latest occurence :

Friday, December 14, 2012 - 14:07
Duplicate entry '2-386-298-0' for key 1 query: INSERT INTO webform_submitted_data (nid, sid, cid, no, data) VALUES (2, 386, 298, '0', 'Να είναι υπό έλεγχο, ενώ απαγορεύεται η είσοδός τους στη θάλασσα') in /home/blueflag/public_html/admin/includes/common.inc on line 3579.

In the attached file there is a (partial) export from the watchdog table.

Any ideas on what might causing this?

I am also having the same issue with Multi-page form. In production we are getting this issue during the heavy traffic.

Any ideas on this ?
