ArcGIS Server 10 SP4 logs below entry in log file. We have a single map service with 100+ layers which has Maximum time client can use a service is 600 seconds (10 min). I am really surpised when some of requests failed with below message. I could not understand (or believe) which request to map server is taking more than 10 min. Can some one throw some light on this? I read all ESRI documentation and forums.
A request to obtain a free ServerContext has failed because the Wait Timeout Interval has elapsed.
