Glassfish v4 sends sometimes empty response to "curl -o testin.txt "my.server.com" under load / access.log shows http OK
normally the Server sends the standart index.html as response, but sometimes curl says "curl: (52) Empty reply from server".
Where can this empty responses come from?
I'm using glassfish v4 from today
I have 2000 Treads in the corresponding thread pool
I have 4 acceptor threads
My connection queue is unlimited
=> The Empty responses are marked in the accesslog as http 200 (OK)
The load peaks around 5% (so it's not heavy load)
What component does this, how can I debug this further.
