I'll try to get more info. What particular server logs are you interested in?

Also, this will be a little hard to reproduce as the server has to be in a partial crash state: i.e. it still has to be responding to open connections, but no response is made on the connection. Of course, I'm still not sure why/how the web server died in the first place so I'm trying to investigate that as well. ;)

Thanks.

I am quite sure that we had this Problem on our test-cluster.
And I am quite sure that it has not been a real ldirectord-Problem.
Unfornatly I can't remember how it was solved (if it has been solved).

Can you please send some kind of Information about the webserver-logs ?

In my LVS cluster I think I may have found a bug in ldirectord.
It seems that if a web server opens a TCP/IP connection, but does not
respond on that connection, ldirectord hangs waiting for a response and
never continues checking the other servers.  I had checking set to
'negotiate' to detect that exact problem, but it ldirectord just sits
there.  A stack trace on ldirectord just says:

read 3)

and sits there.  I'm not sure if it's just for http or https connections
or both.  I'll have to investigate more, but I think it's just https
connections.

The read should eventually time out and ldirectord should
be able to procede. Please let me know if this is not the case.
