 The HS operator in https://lists.torproject.org/pipermail/tor-
 dev/2014-December/007956.html saw this Tor log:
 {{{
 Dec 11 13:08:59.000 [notice] We'd like to launch a circuit to handle a
 connection, but we already have 32 general-purpose client circuits
 pending. Waiting until some finish. [268 similar message(s) suppressed
 in last 600 seconds]
 }}}

 His network seems to be flaky so this might be the result of crappy
 network. However, we might want to investigate a bit further, since that
 message was supressed 250 times.

 I can imagine situations in very busy hidden services, where 32 clients
 try to access them at the same time, which means that it tries to
 establish 32 circuits at the same time which might cause this problem.
