    [ https://issues.jboss.org/browse/ISPN-5221?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13043634#comment-13043634 ] 

Galder Zamarreño commented on ISPN-5221:
----------------------------------------

Yes, apart from the server side logs, the client configuration might be important here. In particular, the options passed in to the RemoteCacheManager in construction.

Also, if you happen to have the GC logs from the server, that'd be great to see what kind of pauses does the server suffer.

Finally, I think we can still improve the code in the event listener to better handle `java.net.SocketTimeoutException` instances when trying to read an event. At the moment, it seems like that after such exception the event listener thread stops its work. I think we can do better than that.

However, I'd still would like to see the logs, GC logs (if available) and client configuration to see if there's something else.

> Using the LAZY nearcache (new in 7.1.0Final) when a java.net.SocketTimeoutException occurs against one of the given HotRod server the RemoteCache becames not usable any more
> This happens very frequently in our DEV environment, but I cannot reproduce it inside a test case
> This is the stacktrace
