did anyone use a soe with the arcgis service?

I'm using an SOE.  I had this same problem after enabling the debug Settings under GIS Server -> Extensions -> Debug Settings and setting the port range to 9000 - 9005.  Once I disabled debugging of extensions, the error wend away.

although this thread is quite old, I've had the same problem recently. I solved it by doing the following: I reassigned privileges to the arcgis server account (just the wizard) and restarted the server. AGS is behaving perfectly well again.

Hope this helps.

It worked for me too, at least until now.
