That's quite the error right? In just about every farm I have setup so far, I am getting this error: "The sandboxed code execution request was refused because the Sandboxed Code host Service was too busy to handle the request"
I haven't quite figured out exactly what the problem is, the ULS logs don't help much, they simply give a IPC error. I have double checked everything. Not sure what happened in RTM that changed from BETA.
I have seen the ACL fix, but that's for a domain controller. Even applying the fix, it still won't go :(
