While my relay server isn't in the same broadcast domain as my backend servers, there is on average 2ms rtt between the systems. Average response time from the HTTP servers is about 300ms. > The error reporting is a bit confusing and should just mention that a > timeout occured, I will fix that.

I hate to say this Pierre-Yves, but this occurs even with a timeout of 5000ms in my configuration file. The *very* same system, polling the *very same* hosts with hoststated does not have this problem. > > > startup > > > init_filter: filter init done > > > tcp_write: connect timed out > > > relay_privinit: adding relay www > > > init_tables: created 0 tables > > > hce_notify_done: aa.bb.cc.209 (tcp_write: connect failed) > > > protocol 0: name http > > > host aa.bb.cc.209, check http code (3ms), state unknown -> down, > > > availability 0.00% > > > flags: 0x0004 > > > tcp_write: connect timed out > > The timeout is mentionned here. # grep timeout /root/relayd.conf timeout 5000 > > > > type: hce_notify_done: aa.bb.cc.211 (tcp_write: connect > > > failed) http > > And then a connect failed error happens which might have confused you. If you look here, the connect succeeds..
