Server Busy Error - Sap GUI 7.60

[Jaap5FCD]

Hi, 

we have a issue with Acrobat 2017, while opening  PDF files generated in SAP GUI 7.60 ( and older versions) the "Server is busy - switch to - retry error" pops up. This is happening for longer then a year now.

We are running the software on Win2012R2  with Acrobat 2017, both fully up to date. 

The Server is busy error is popping up when opening a generated PDF from SAP GUI. This does not happen everytime, it happens a few times per day on different users on different machines and clicking on Switch to or retry does nothing. User has to close SAP  GUI  via taskmanager and retry.

The official vague reason is:
"The reason this error is popping up is as the computer or a particular program is not releasing the desired resources and so the program cannot be launched." 

The generated PDF file itself opens fine (it is located in the user %temp%).

 There are zero logs in eventviewer, adobe logs or SAP GUI logs. So there is no way to tell wich program is causing this. Even with procmon logging it is hard to say.

What have we tried:

- Close every possible process and try again. The popup does not go aways, user has to close (via taskmanager) SAP GUI
- Virus scanner disabled
- Completey reinstalled the Win2012R2 machines (it occurs on more then 1 machine)

- With older versions of SAP GUI the error is also popping up. 
- Superfetch windows service is disabled (https://helpx.adobe.com/lightroom-classic/kb/server-busy-error.html)

- Many more..

Odd thing is the error does not occur when we use another PDF viewer as default, so we have the feeling Acrobat 2017 is causing this. 

Is there any way to trouble shoot this issue, and to determine the cause of this?

Just curious if disabling some Sandbox protections, like for example, "Protected Mode (View) at StartUp", will have any impact and also if your Acrobat Pro needs to be updated.

If you haven't applied the latest update yet, I think that this issue is related to the Sandbox protections of Reader/Acrobat since this was addressed in the last update. But if you did applied this update and you still get this problem then disregard this observation.

Also, your version of SAP GUI published a new patch and it does include a new feature that allows the  users to import/export their settings to another installation. See this discussion: https://wiki.scn.sap.com/wiki/display/ATopics/SAP+GUI+for+Windows%3A+Important+News

Additionally,  take a look here: https://assets.cdn.sap.com/sapcom/docs/2016/06/586c0458-767c-0010-82c7-eda71af511fa.pdf   specifically this note:

• "Windows 7 / Windows Server 2008 / Windows Server 2008 R2  --   Microsoft ended support for these operating systems on 14th of January 2020 (see also https://support.microsoft.com/en-us/help/4057281/windows-7-support-will-end-on-january-14-2020 and https://support.microsoft.com/en-us/help/4456235/end-of-supportfor-windows-server-2008-and-windows-s...). This means that SAP GUI for Windows is no longer supported on these platforms since 14th of January 2020. If you are still using one of these operating systems, please upgrade to a supported
  operating system. Even if you have purchased extended support from Microsoft, SAP support will not work on issues which are only reprocible on a non-supported operating system."

Now, you've also mentioned about PDF files generated using SAP GUI. But where are these files saved to? And are you also using Hyper-V?

In any case, after reading the notes above I am curious if the Acrobat Pro DC 2017 integration with MS Windows is either breaking or just restricted because of the Acrobat Sandboxing protections inherited when the PDFs were created.  Other PDF viewers may not have the same Sandboxing protections (restrictions), so it may be worth looking into these settings in the Acrobat Preferences, OR,  restoring the users' default user settings in the SAP GUI clients using NWSAPSetup   as explained in the SAP wiki link above.

Hi,

We have exact the same issue with SAP and reading documents from Record Management, that are kept in the SAP content server. We are hosting the SAP environment for this customer. The Workplaces at customer side ar running on a Citrix platform that is provided bij another supplier. It looks likek that this problem is only seen at the Citric workplaces.

Can you confirm if the problem disappears when you disable automatic updates and also check if Acrobat (or any other program) needs to be removed  from the startup folder.

How to troubleshoot this error is fully explained in these links:

• Server-Server busy- Switch-To... 

• fix-error-server-busy 

Also check if the server busy error is caused by another Adobe Creative Cloud application and not necessarily Adobe Acrobat.

I have seen something like this before, please check the size of the users "Temporary Internet Files" folder in IE11, yes i kid you not, the reason is if you have set aside maybe 250Mb or more for temp files, the PDF file is placed in the temp folder, but enumerating takes to long due to way to many files, and Adobe times out, hence the error message, decrease the "temp" sixe to below 50 mb, and test.
