Re: Fwd: websocket connections consume too much memory
Hello All,
Maybe this behavior is caused by the fact defaultMaxSessionIdleTimeout
is not set for websockets?
Can be updated as follows
final WsServerContainer sc =
(WsServerContainer)getServletContext().getAttribute(SERVER_CONTAINER_SERVLET_CONTEXT_ATTRIBUTE);
if (sc != null) {
sc.setDefaultMaxSessionIdleTimeout(60 * 1000L);
}

Re: Fwd: websocket connections consume too much memory
I retest with
*8.5.38*
...
org.apache.tomcat.embed
tomcat-embed-websocket
${tomcat-embedded.version}
org.apache.tomcat.embed
tomcat-embed-core
${tomcat-embedded.version}
org.apache.tomcat.embed
tomcat-embed-el
${tomcat-embedded.version}
org.apache.tomcat
tomcat-annotations-api
${tomcat-embedded.version}
The result is the same
I also checked status of the sockets on server with the netstat command.
The number of ESTABLISHED is constantly and rapidly growing.
Note, the problem is reproduced as a result of load testing.

Fwd: websocket connections consume too much memory
Hi everyone!
I encountered a problem with embedded tomcat 8.5.29 (part of spring boot
1.5).
The number of websocket connections that are stored in a variable
"*connections"
(look below) *is increasing indefinitely.
package org.apache.coyote;
public abstract class AbstractProtocol implements ProtocolHandler,
MBeanRegistration {
...
protected static class ConnectionHandler implements
AbstractEndpoint.Handler {
...
private final Map connections = new
ConcurrentHashMap<>(); // <-- The number of websocket connections that
are stored in a variable is increasing indefinitely
...
}
...
}
As a result websocket connections consume too much memory.
I see the reason for the fact that the socket remains in
the SocketState.UPGRADED state even after closing the websocket. Although
expected SocketState.CLOSED.
