Hi Guys,
I have a multi-threaded server written in non blocking NIO (one
thread handles the IO) and after a while i see that it uses
about 90% CPU. I managed to find the thread that causes the problem, and
it is the one handling the IO but i need help understanding the
reason for it, please take a look:
Thanks
I noticed that the problem only started after I got a null pointer
exception in the line: connectingChannel.write...
The thread has a while(true) loop surrounding a try...catch... that
catches this exception and continues normally.
The reason for the 90% CPU is that ioHandlerSelector.select(1000)
returns immediately (after the exception), and it's surrounded by a
while(true) loop (Every 1-3 ms i see a "no ready channels" msg)
What can be the problem?
Thanks again
