Bug ID: 59710
Summary: java.io.IOException: Connection timed out
Product: Tomcat 7
Version: 7.0.69
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: WebSocket
Assignee: [email protected]
Reporter: [email protected]
Hello,
We are using Tomcat 7.0.69 and suspect a bug with session.close() when
"Connection timed out" happens sporadically. When the exception is thrown
@onError correctly is called and I call session.close but the connection is
still open in limbo which cause memory leak.
On the client we use Tyrus with reconnectHandler and set HeartBeatIntervall to
1 minute. When the timeout exception is thrown in Tomcat, Tyrus is still happy
with the connection even though its closed in Tomcat.
My theory is that there is a problem with session.close() when a timeout
occurs. It never really gets closed.
I have set the connectionTimeout=-1 connectionUploadTimeout=-1 in server.xml.
Anyone has a clue?
BR,
Hugo
