Hi,
I can reproduce the following problem pretty easily
on FreeBSD 9, 10, CURRENT.
(1) Install the devel/jenkins port
(2) Run:
service jenkins onestart
(3) In /var/log/jenkins.log, I see a traceback:
WARNING: UDP handling problem
java.net.SocketException: Invalid argument
at java.net.PlainDatagramSocketImpl.join(Native Method)
at
java.net.AbstractPlainDatagramSocketImpl.join(AbstractPlainDatagramSocketImpl.java:168)
at java.net.MulticastSocket.joinGroup(MulticastSocket.java:300)
at hudson.UDPBroadcastThread.run(UDPBroadcastThread.java:76)
Feb 22, 2014 5:21:00 PM hudson.WebAppMain$3 run
I reported this bug against Jenkins:
https://issues.jenkins-ci.org/browse/JENKINS-21727
but now I suspect that this is a FreeBSD bug or
implementation with respect to multicast.
Can someone help me debug this and isolate the problem?
It's been a while since I've debugged Java code.
Thanks.
