Hello, I m using tomcat 8.0.21.
I want to send *up* to 4 MB of text messages through a websocket connection to my tomcat server. I set the MaxTextMessageBufferSize to 4 MB.Now as a result, every time I open a websocket connection and I send a message , I can see that 4 MB are being allocated in memory for the CharBuffer messageBufferText regardless of the size of the message I send . 99 % of my messages would be way smaller.The 4 MB remain allocated in the messageBufferText CharBuffer even after the message is handled. The connection can stay open up to 30 minutes in my case, and each websocket connection is taking 4 MB of memory all of that time even if it's inactive which leads my server to eventually run out of memory even with inactive connections . Note that I m using a Whole Message Handler. Why not set the messageBufferText CharBuffer size to the payload length if it doesn't exceed the maxTextMessageBufferSize, and then clearing that buffer ( reducing its size) after the message is handled by the Handler, so that inactive connections don't take up memory. ( same for the binary) ? Any other / better suggestions on how to solve that problem ? Thanks.
