Hi, 

In the HttpsServer log file we keep getting these two errors (often many each minute) :

(OS 10054)An existing connection was forcibly closed by the remote host.  : ap_get_brigade() didn't read data

(OS 10054)An existing connection was forcibly closed by the remote host.  : Error processing websocket connection

Any ideas what can cause this? We experience that login can be slow sometimes, and we think that this might be correlated to this issue. We have around 1250 active users (Around 700-800 are active each day). We are currently running upd15 (but this was also a problem for previous updates).

This is how our HttpServer config look like:
