    Hi Bowen,
    I've checked the local agent has been offline at 2014/09/05 18:00:00 UTC+8, as the shop close every night and they will shut down the computer, but they've turned on the computer in next day morning, and they keep turning that off at night, turn
    back on at next morning.
    I've checked the agent was online during that "stuck" period when the computer was turned on, as I could click the "PING SYNC SERVICE" and it reported it could reach the sync server, and I could also view from the portal that the agent
    was online, just the sync group stuck in the "processing" status.

    As the client need the sync to be fixed ASAP, cannot wait for the answer / help, I've removed the sync agent, compare the data (what data need to download from Azure to client, what data need to upload from client to Azure) and recreate back the sync group.
    Hi Micheal,
    Is this the workaround in your scenario? Since the Azure SQL Data Sync failed, the Microsoft support engineer will help to solve the problem from backend based on your subscription ID and Sync Group ID. Sometime delay might be expected. Your patience is
    greatly appreciated. Thank you for your understanding and support.

  • Data Sync stuck in processing

    Can you please delete my data sync? I tried to cancel the data sync, so I could delete it but it has been stuck in processing for almost 24 hours now. The subscription id is 2b362515-3f77-44fc-9803-08334705d01a and the sync group is called DevSyncGroup.

    Hi CpAtMtb,
    Thanks for your information about  subscription ID.
    The Microsoft support engineer will help to solve the problem from backend. Sometime delay might be expected. Your patience is greatly appreciated. Thank you for your understanding and support.
    Besides, any of the following can result in a sync group being stuck in the processing state.
    • The client agent is offline.
     Be sure that the client agent is online then try again.
    • The client agent is uninstalled or missing.
     If the client agent is uninstalled or otherwise missing:
        1. Remove agent XML file from the SQL Data Sync (Preview) installation folder if the file exists.
        2. Install the agent on same/another on-premise computer, submit the agent key from the portal generated for the agent that’s showing offline.
    • The SQL Data Sync (Preview) service is stopped.
        1. In the Start menu, search on Services.
        2. Click Services in the Programs section of the search results.
        3. Find the SQL Data Sync (Preview) service.
        4. If the service status is Stopped right-click the service name and select Start from the dropdown menu.

  • Sync stuck in Processing

    Hello!
    My Sync group is stuck in Processing status, and I'm unable to make changes or sync data anymore. This is in a production environment, so it's disruptive to our reporting processes.
    Here's the error:
    Sync completed with warnings in 259403.73 seconds. Upload:   0 changes applied/0 failed  Download: 0 changes applied/789 failedData Sync will stop synchronizing changes for this sync group member in 39 days if the failures are not resolved.

    Sorry for the late delay...
    ece4bf55-7077-420b-8c83-1cbf2f8c44d7_East US - both databases that are part of the sync group are still showing as Processing on the Properties screen. The sync itself fails with this error:

  • Sql Azure Sync - Sync Group stuck in "Processing..." state

    I am experiencing 4 of my sync groups being stuck in "Processing.." State
    It seemed to happen when connection to the agent was lost. It has not synced now in 20+ days and although agent now connected, sync groups just keep saying "Processing...."

  • My sync group is stuck in the processing state

    The database sync that we have configured has been working for months and suddenly stopped successfully running 1/19/2015 2:19 PM Pacific Time. We have the sync configured to automatically execute every 5 mins and I even tried to run it manually. The job
    stays perpetually in a "Processing" state with no additional info (e.g. error, warning, etc).
    Can anyone provide assistance? (e.g. reset the sync status, provide detailed logging as to the cause of the issues) What is the proper course of action? (e.g. reconfigure the sync service, etc) Please advise.

    Hi,
    Thanks for posting here.
    Any of the following can result in a sync group being stuck in the processing state.
    a)The client agent is offline.
    Be sure that the client agent is online then try again.
    b)The client agent is uninstalled or missing. 
    Please check the above and try to sync again.
    In the mean time we would check from our back-end. It may take more time than expected.

  • Updates getting stuck in V2 processed state

    Hi,
    In our ERP production system EP0, update entries are getting stuck
    in 'V2 Processed' state.
    Details of the same show that the collective run state is in initial
    state for functional module 'MCEX_UPDATE_03'.
    Please find the attached screenshot of details.
    These updates are gettin stuck for specific transactions like MIGO.
    We have already tried running the report RSM13005 but it has not helped.
    Please look into it urgently as the system is a production system.
    Thanks in advance.
    Regards,
    Suresh
    Edited by: suresh k on Sep 26, 2008 2:38 PM

    Hi
    As you checked in transaction SM13 they are stucked in Initial state. There was various states associated with the update like INIT and ERR.
    What is INIT status:
    Update records which have not yet been processed have the status INIT or AUTO. INIT refers to a complete update record (header, function module call of update and data elements are present), which has not yet been processed however.
    What to do: SM13 -> Update records -> Update -> All records/Single
    you can set the update administration so that all records with the status 'INIT' or AUTO' (all update records which have not yet been updated) are processed (as far as possible).
    Warnings: please check with the user who posted the updates in the first place - make sure that they have not already reposted the update manually. If you are in doubt, please re-enter the data manually rather than using this update function.
    Hope this helps!!
    Kind Regards

    Hi,
    After investigation I found the sync stuck is caused by your local agent offline. We've already released a hotfix to avoid stuck in this scenario.
    And currently our backend shows that the related sync group is already removed, could you please let me know if there are any more question?
