As I've read in CA documentation, some time ago the behaviour of CA
library was different. The clients tended to start new search just as
soon as they discover that connection is "unresponsive". But in the
current version they wait until TCP connection goes down (and as you
mentioned it may take pretty long time if the connection is not closed
in a "polite" manner). So is there any configuration variable or some
other way to choose which behaviour we need ?
 

Artem.
