Thread:Support/View-pool-error/reply (2)

So when does this error actually occur? (For context, here is a screenshot of the error message and the pagieview stats for the article in question. Even though the stat counter hasn't been working for the last few days, so there is no sure way to check, I find it hard to believe that there had been a sudden interest about this small US island strong enough to overload the servers.)

The error seems to be thrown by  in , and the comment at the end of   suggest this is not something that should normally happen, even when the number of threads hits the limit (that would be the   branch, I suppose). So this seems to be an "unknown error" error rather than a "too many requests" error, and the message misleads users into thinking the server is overloaded when there is actually some more serious error. (In this case a bug in the PoolCounter extension, according to Tim's comment.)
