SPListItem.Update() => Thread was being aborted.

Hello,

I currently have a problem to update a mysite list item.

This code is working very well on my dev environment but in the production it's not working :/

My logs end with : 

• ...
• Item added
• Error: Thread was being aborted.
• Nok: Thread was being aborted

Anyone have an idea? (on prod the mysites are in a separate web application. that's the only difference)

Thanks

public static object Add(String User, String Title, String Text) 
        {
            try
            {
                String AuthorLoginName = SPContext.Current.Web.CurrentUser.LoginName;
                SuiteBarLog("Sender: " + AuthorLoginName); 
                SPSecurity.RunWithElevatedPrivileges(delegate()
                {
                    SuiteBarLog("RunWithElevatedPrivileges");
