Critical I've setup Jenkins on windows in our internal network to build our projects. But Jenkins regular crashes a few times a day, with one crash always happening around 5:20AM.
And all crashes seem begin with event like below
[JNLP4-connect connection from 192.168.20.90/192.168.20.90:53854] Refusing headers from remote: buildbox8 is already connected to this master. Rejecting this connection.
And proceeds to
IOHub#1: Worker[channel:java.nio.channels.SocketChannel[connected local=/10.10.0.28:53724 remote=192.168.20.90/192.168.20.90:59087]] / Computer.threadPoolForRemoting 693 for buildbox8 terminated
