CRM 2011: Sandbox plug-in execution failed RRS feed

    I'm getting the following error when a plugin running in the sandbox executes in my environment:

    The plug-in execution failed because no Sandbox Hosts are currently available. Please check that you have a Sandbox server configured and that it is running.

    I look at the trace log and I see one for the HostService with the following entry:


    [2011-04-22 11:34:45.781] Process:Microsoft.Crm.Sandbox.HostService |Organization:00000000-0000-0000-0000-000000000000 |Thread:   77 |Category: Exception |User: 00000000-0000-0000-0000-000000000000 |Level: Error | CrmException..ctor

    >Crm Exception: Message: Assembly should be provided, ErrorCode: -2147204719

    Any hints as to what is going on? The plugin works just fine outside of the sandbox, and isn't doing anything that violates sandbox constraints...

    This turned out to be a bug that was quickly resolved by Microsoft in UR 2 and already rolled out to CRM Online. If you see this issue, make sure you are up to date on rollups!

    open a command prompt on the appropriate server as an administrator and enter:

    net start mscrmsandboxservice

    Let me know if this does not fix

    I get a message that the service has already been started. So, just for kicks, I stop and start it again. When a plugin executes, I again get the error message, and the trace log has another entry saying "Assembly should be provided".

    Researching this further, it appears to be a problem when the plugin assembly is greater than 6750KB. If I remove enough code to bring the assembly under that limit, things work great. It has nothing to do with the code I removed, because if I add that code back, and then remove other code to get the assembly size back down, it continues to work.

    Anyone seen anything like this? Or can anyone disprove my theory by saying they are successfully executing sandbox plugins in an assembly larger than 6750KB?

    We are on rollup 2 (on prem) and face this issue. Also, my assembly size is just 40 kb so the theory KTurbyfill posted on April 27 2011 is disproven.

    There was no change to the plugin code. It suddenly stopped working. My hunch was that there was something wrong with the sandbox service but I can't find what.
