ping delay time
Hi,
I'm using clojure client of zookeeper, after connecting to zk server, my
client keep pinging zk server
instantly. here is my debug log:

how can I set a delay for each ping ?
Re: ping delay time
Posted by Flavio Junqueira <fp...@apache.org>.
Client sessions are pinged and the frequent pings indicate that the session timeout is set too short. The server will have the right timeout (min 2x tickTime), but it is possible that the client isn't setting it right, but it is a guess.

Hmmmm so it abnormal. I'll dig more. But is there any related feature in zk?

Hi there,
We don't really support this clojure client, so I'm not sure why it can be sending this many pings. Perhaps there is an issue with the session timeout value it is keeping?
