Hi Jan, Connection loss means that the client has disconnected from the server it was connected to and it will try to connect to another server to avoid session expiration.
Session expired means that your session has expired. :-) Session expiration is important because if you have ephemerals associated to that session, they will be gone, so it might trigger some recovery path in your application. You're using the C client? If so, then it is not going to be garbage collection on the client side causing your clients to disconnect, which is a pretty common cause for applications using the Java client. You may want to investigate if you're having some network issues or if perhaps your servers are overwhelmed with something. If you're sharing the disk devices and other applications are inducing a good number of IOs, then you may end up affecting the performance of the server. -Flavio > On 12 Aug 2016, at 15:39, Krizansky, Jan <[email protected]> wrote: > > <html><bodyHi ZK group, > > I'm trying to reach out to you as we couldn't find any satisfying info online. > We've recently started seeing some errors in our cluster.
