Because when i stop app-1, mod_caucho also stops to deliver to app-0, even caucho-status shows green for it. Also the other way around, if i stop app-0, it also stops delivering to app-1. Interesting is also, what caucho-status shows: Default Virtual Host Error: host unavailable/busy Source: Cache File (/tmp/172.17.32.4_6800, Thu Jan 1 01:00:00 1970 ) Last-Update: Thu Jan 1 01:00:00 1970 And shortly later without "host unavailable/busy": Default Virtual Host Source: Cache File (/tmp/172.17.32.4_6800, Thu Jan 1 01:00:00 1970 ) Last-Update: Thu Jan 1 01:00:00 1970 And then again later: Default Virtual Host Source: Resin-ETag (Wed Feb 13 19:26:21 2013 ) Last-Update: Wed Feb 13 19:26:21 2013 And hopping between all that. > > > > > And second: when i disable (not stop) a resin in a cluster, why > caucho-status still shows it in green as "ok"? > > Because mod_caucho can still connect to the backend Resin.

It would be totally awesome to have a way to take the server out of load balancing for mod_caucho, without having to stop it. The server should be happy and alive for whatever, maintenaince, calming down, resin-admin and so on. In the old days, there i would just remove the server from apache's local resin.conf and mod_caucho was happy with it. And Resin as Loadbalancer: this would open more issues for me right now and is a tough decision: perl, mod_proxy, lots of rewrite rules to convert. First i need to sell resin4 anyways. :) _______________________________________________ resin-interest mailing list resin-interest@caucho.com http://maillist.caucho.com/mailman/listinfo/resin-interest
