Hello,
I have been struggling with memory problem for a while. For some reason the
memory (1,3 GB) get full after some days of usage.
Im using websocket to send and receive queries to client connected with Tyrus
with the following function.
The WsPayload is stored in the session userproperties and later ofcourse
removed.
I have a dump file of the heap and I see with Mat abnormal amount
org.apache.tomcat.websocket.server.WsFrameServer objects each occupying 5MB.
There is no relations between amount of objects and sessions. The sessions are
about 30-70.
The dump file is 30 MB so its not possible to attache it but will attach a
screenshot of MAT
@OnMessage
public void onMessage(Session session, final ByteBuffer message) {
try (ByteArrayInputStream ins = new
ByteArrayInputStream(message.array());
ObjectInputStream in = new ObjectInputStream(new
GZIPInputStream(ins))){
WsPayLoad sPayLoad = (WsPayLoad) in.readObject();
WsHelper.putRespWsPayloadsSess(session, sPayLoad, message);
} catch (IOException | ClassNotFoundException e) {
e.printStackTrace();
}
}
BR,
Hugo Larson
