Hi,
I'm using commons-httpclient-3.0.1, jre 1.6.0_16. I have a situation
where I'm using the HttpClient to do a get, and the call hangs. The thread
has hung at java.net.SocketInputStream.socketRead0. I've set the socket
timeout at two points:
default timeout:
MultiThreadedHttpConnectionManager.getParams().setSoTimeout(60 * 1000);
method timeout:
GetMethod.getParams().setSoTimeout(30 * 1000);
This bug is tough to reproduce, but I have a system in this state. Getting
the heap dump, I double checked the value of the socket timeout, and it is
still set to 30 seconds, as expected.
I'm sorry if this is the wrong place to post (considering the issue seems
to be in java.net.SocketInputStream), but I wanted to see if anyone had
come across this situation.
Thanks,
