    This update has, unfortunately, still a serious bug in the “SPTimerRecyleJobDefinition”. The job is never executed correctly!

    public override void Execute(System.Guid targetInstanceId)
    Process currentProcess = Process.GetCurrentProcess();
    if (System.DateTime.UtcNow.Subtract(currentProcess.StartTime).Minutes < 60)
    ULS.SendTraceTag(7436320u, ULSCat.msoulscat_WSS_Timer, ULSTraceLevel.Medium, "Skipping timer recycle since the process has been running less than 1 hour.");

    TimeSpan.Minutes is the Minuts Fragment and can not be greater than 59 (TotalMinutes is correct)! This Job is never executed!!!!
    The next Bug is Utc. The Process.StartTime is local time (Kind=local)

    Please remove the term review so that you can always restart the timer safely!

    1. Hi Thomas,

      if you Need this issue to be investigated I would recommend to open a support Case with Microsoft.
      Blog comments are not sufficient to start investigation and hotfix development.

        Hi Stefan,

        Microsoft professional support cannot create a internal ticket for the developer or product department.
        Answer from professional support is use premier support or this forum

        This is a Bug not a Feature (OMG). The interest for stable products is not so great 🙁

    Hi Stefan, is this and other recent monthly updates a server (uber) or CU update? In the sense that you define these terms, Thanks

    1. Hi John,
      for SP2016 there are no Uber packages as there are only 2 Hotfix packages per CU. This is different from other SharePoint versions where potentially dozends of hotfix packages were released and it was nearly impossible to keep track about what to install when skipping a couple of CUs.
      With only 2 fixes the Need of an Uber or Server package is gone.

      1. JohnC says:

        Hi Stefan, I’m not clear as to the implications of your reply. My goal is to ensure that all components of SharePoint 2016 are fully patched to latest available regardless when each component was last patched.

        Do I have to apply each monthly SP 2016 CU in turn, or do I apply only the latest CU?

        Ie is each SP2016 CU what in your earlier blog post would be considered an “uber” patch that contain all updates including for components that have not changed in the last month?

        1. Hi John,

          you have to install the latest language dependent and language independent fix. Thats all.
          For some CUs there is only one of these two – in this case look for the latest one of the other in prev CUs.

          As there are only 2 patches to look at rather than dozends as with SP2013 the product group decided not to create Uber packages for SP2016.

    Hi Stefan, Thanks for your posting. There are two CUs each month

    Update for SharePoint Server 2016 September 2016 (language independent)
    Update for SharePoint Server 2016 September 2016 (language dependent fixes)

    Our SharePoint 2016 farm is English only. Which one should I deploy? Should we apply both?
    Thanks in advance,

    Hi Stefan,

    So the correct way to install SharePoint 2016 updates will be:
    1) Install Language dependent + Language independent updates (binaries)
    2) Run the SharePoint configuration wizard ?

    Also, can we skip updates ? Like install RTM then install directly the updates from September 2016 for example ?


    1. Correct. Of course you can install September CU directly on RTM as they are cumulative.
      Only be aware that sometimes there might inly be one of the fixes in a CU because in that month no fixes for the other package was created. Then you need to install the most recent one of the other package.
      I will mention that in my blog posts if this is the case.
