Re: windows 7 slaves intermittent disconnect I had the same issue here with 20 slaves on a Jenkins cluster running 107k JUnits all at once, the issue turned out to be the high ping time between the slave and master. After I put them onto a dedicated switch with the same vlan upstream my problem went away. I also noted that the high load on my build machine causes a considerably higher ping time in Jenkins only. Possibly to do with the way the Slave is written and nothing to do with the network.

Re: windows 7 slaves intermittent disconnect

It is not possible to diagnose this issue without an agent log from the remote side. Over there last year there were many fixes in the Remoting stability area + JNLP4 changed the remoting NIO management significantly. I am going to close this issue as a duplicate of a similar one. Please provide more details there if it still happens on the new version. If you use vMotion by a chance, there are known issues with it
