and right now I dont recv any useful datas

UPD:
it's working right now (13:44 UTC)
UPD2:
it's working if wait connected sometimes 20 minutes and sometimes 0 minutes and sometimes "never". very strange and no good.
can someone's debug session stops sending messages to other users?.. who knows implementation of socket.io server?
To MtGox:
maybe it's sabotage.. Slow Read DoS attack.. bad guys overflow send pool with slow connections and.. voila!
will be better for all clients drop connections that cannot read string, i.e. send to client not finished for.. hmm.. 0.5sec! +ban by IP 10min (epoll, select or other asynchronous mechanism). I took digits from air, I dont know % loading for servers machines and number of connections.
p.s. ping ("2::") works always
