We have 2 websites set up - one on staging and production. We have set up site sync between 2 servers from staging to production and everything is working fine.
Problem appears sometimes when Site Key on target server resets to 1 (original value is 2) and users are not able to sync between staging and production. Site Key on staging server is set to 1 and production server is 2 but Site Key changes to 1 unexpectedly on production server and we need to change this manually to 2 to get Site Sync to work.
I see entry in trace.log file every time Site key is changed to 2, but I do not see entry for change to 1, so I am not sure what is causing that change. Also, as per what I understand Site Key is saved in DataConfig.config file but even when on admin screen site key shows as 1, it is still 2 in DataConfig,config file which makes me believe that it is being changed in memory somehow and creates the problem.
We are not using load balanced environment at the moment and Website config is saved in files (not in database).
I opened support ticket with telerik on this and they are still checking what may cause this. Until I have any feedback from support, I would like to see if anybody else had/have this problem and solution to this.
If you have any questions about the environment/need any additional information, please let me know.
Thanks in advance
