Piwik hexadecimal generation issue


I have already posted in the forum about the data missing from the msql db once we refresh the UI of Piwik.
We also found out that the empid which we have captured using custom variable is changing for the same actions.
The screenshot for the statement above is attatched with the mail.
Also I had informed some 1000+ actions are triggered for a single person for a single visit.
The screenshot of this problem is also attatched with this mail.
Please go through this issue and provide us with a solution.
Looking forward for your support.
Thanks in advance :)!!!
