Sandboxed code execution request failed - Resolved

Today’s article is based on Sandboxed Solution. By means of this article, I am going to share some issues that I faced while activating the solution as well as adding the webpart on SharePoint site.

So basically what is Sandbox solution?
When we talk about ‘solution’ then only one term which will comes to your mind i.e. WSP (Windows Solution package). People often misunderstood this Sandboxed concept as something is going to affect the farm, the scope is based on web application, and it’s going to reset the IIS app pools but let me tell you the fact – Sandboxed solution are user code solutions. Now again the new terminology – what is ‘user code solution’?

One process leads to understand a new process- isn’t it interesting? J

User code solution means user himself can deploy this solution and activate it and does not required SharePoint administrator to deploy. This is a very fine concept in which the scope is restricted to the specific site collection only. I don’t want to talk about ‘farm Solutions’; otherwise this will misinterpret the purpose of this article.

Why Sandboxed solutions are so important:
Sandboxed solutions do not run in the IIS worker process, neither the IIS application pool nor the IIS server must restart.
It is not necessary for the SPUCWorkerProcess process to recycle to load the latest version of the solution.

Problem description:
One user opened a ticket by saying ‘he needs to deploy some package’. Further probing, I came across that he has a WSP file and wanted to use as Sandboxed.

Now the question is – How to configure Sandboxed if it’s not there in your farm?

Here are the details steps:-
Section: 1
1.      Open Central administration
2.      System settings
3.      Under Servers
4.      Manage services on server
5.      Activate this service “Microsoft SharePoint Foundation Sandboxed Code Service”

Section: 2
1.      On the same server which is hosting the Sandbox code service
2.      Click on ‘start’
3.      Administrative tools
4.      Services
Once this configuration done then you are ready to upload the WSF file to the solution gallery. – Where is this solution gallery?
·         Open your SharePoint site
·         Site actions
·         Site settings
·         Under galleries

Note: Make sure you have site collection admin access to upload the solution in the solution gallery.

Once the solution gets uploaded then you can activate that solution.
How to activate it? -> Click on the solution dropdown -> you will get the option of activate.

In my case, user was trying to add a webpart on the home page of the site but as soon as I select the webpart to add then boom! It throws an error message as following-

Sandboxed code execution request failed.

Let me tell you some story behind this: I have enabled the service only on the app server and not on the web front ends. So basically if I activate any service on app then it does not necessary to activate it on the other servers (WFE’s) – do you support this fact? – would like understand your views!

I negotiated my thoughts for a moment and started the service on rest of the front ends but then a different error comes into picture: see the following-

The Sandboxed code execution request was refused because the sandboxed code host service was too busy to handle the request.

I started exploring the CA, site collection features, site manage features and one link which caught my attention, that is – Manage User Solutions

Where is this link?
·         Open the Central administration
·         System settings
·         Manage user solutions

Once you will open this section then you will get two options:
·         All sandboxed code runs on the same machine as a request.
·         Requests to run sandboxed code are routed by solution affinity.

It took some time for me to understand these terminologies as by practical only you will come to know the actual results.

See the differences:
All sandboxed code runs on the same machine as a request: Sandboxed Code Service should be started on all the WFE’s.

Requests to run sandboxed code are routed by solution affinity: if you start the “Sandboxed Code Service” on app server only then also it’s fine.

So I stick with my logic and select the second point i.e. Requests to run sandboxed code are routed by solution affinity and disabled the service from rest of the front ends.

But the error is still there! I checked the logs, restarted the sandboxed code service, restarted the user code service but still didn’t make any difference.

Then here is the rescue – In our case we checked the state key value and ours was- 0x00023c00

Actual Resolution:
a)      On the server, click Start | Administrative Tools | Services.

b)      On the Services dialog, scroll to SharePoint 2010 User Code Host.

c)      Note the full user name in the Log On As column. You will need this information later.

d)      Open SharePoint Management Shell.

e)      Enter the following at the command prompt, including all punctuation.

f)       (Get-SPManagedAccount –Identity “username”).Sid.Value

g)      Replace username with the name you obtained in step 3. E.g., Domain\FarmAdmin

h)      This will return the user’s SID (Security ID), which you will use in a later step.

i)        Open the registry editor and navigate to:

j)        HKEY_USERS\SID you obtained earlier\SOFTWARE\Microsoft\Windows\CurrentVersion\WinTrust\Trust Providers\SoftwarePublishing

k)      Be sure the State key value is set to 0x00023e00.

l)        Restart the sandboxed host service on all servers on which it is to run.

No need of server restart as well as IIS RESET.  

Check the results and you will be good.
