beginning to encounter this error:
"It has taken too long to refresh the W3SVC counters, the stale counters are being used instead."
on our IIS6/Win2k3 boxes circumstantially whenever the HTTP requests get in the region of 500p/sec.
Doesn't crash IIS or any of the wroker processes so as far as we can tell the service is not interrupted, but it is causing dr.watson to spawn a process which starts consuming a lot of processor time, which does lead to 503 "Service unavailable" responses.
No clue how to diagnose what's going on let alone fix it, and google/ms is of little use. Any ideas?
