[infinispan-issues] [JBoss JIRA] (ISPN-5221) Java Hotrod client, nearcache broken after a org.infinispan.client.hotrod.exceptions.TransportException:: java.net.SocketTimeoutException

[Enrico Olivelli (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-5221?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13049438#comment-13049438 ] 

Enrico Olivelli commented on ISPN-5221:
---------------------------------------

I checked out your code
IMHO I cannot understand how the client recovers from the readtimeout scenario or even the socket closed scenario, could you please explain ?

This is the scenario:
- I have two hotrod servers
- my client at startup connects to one server
- the connection due to OS or network problems gets closed
- the ClientSideNotifier dies and stops to forward to Listeners

I cannot find where the connection gets invalidated (and the server maybe added to the failed servers list) and a new connection is created

Another question:
in case of a socketreadtimeout is it possible that the "unread bytes" will be read from the next call to readEvent ? resulting in a corrupted stream  (?InvalidResponseException and readMagic ?)

thank you very much

> 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
