Indeed, that *could* be a possibility if combined with a server maxconn because connections would be kept for a long time on the server (waiting for either the client or the server to close) and during that time nobody else could connect. The typical problem with keep-alive to the servers in fact. The 503 could be caused by requests waiting too long in the queue then. Chin Yin, Xani was right, please take a look at your logs. Also, sending us your config would help a lot. Replace IP addresses and passwords with "XXX" if you want, we'll comment on the rest. BTW you should tell your admin that 1.3.21 has an annoying bug which makes it crash when connecting to the stats socket. Thus, this reduces your possibilities of debugging it. When you have some time, you should upgrade it to 1.3.22 or later (1.3.24) which fix a small number of remaining bugs. > example stats page screenshot attached. Nice stats Hank :-) Cheers, Willy
