Hi, Today I created DIRMINA-1070 <https://issues.apache.org/jira/browse/DIRMINA-1070>, but I wanted to reach out to the list to see if anyone could provide any insight into how we can handle this issue in the mean time.
As a short description, when a client connects to our MINA server and specifies a large window size (TortoiseGit for instance uses 2GB) it results in an OutOfMemoryError. Apparently because the DefaultWriteRequestQueue uses an unbounded queue, the server writes data without any throttling and if the client is unable to keep up the heap is eventually consumed and the error happens. I've looked at implementing an IoFilter to try and handle filterWrite and messageSent (to make sure only a fixed maximum number of bytes are ever in-flight) but apparently the calls might be unbalanced because a lot more bytes came through the messageSent call than they did through the filterWrite call. I'll appreciate any help you can provide. Cheers! Juan
