Windows Jenkins master losing Linux slaves..

[Rigdha Acharya]

I have a Windows Jenkins master and I use the swarm plugin to connect slave nodes to it. My Windows slave work fine.

Linux slaves connect to the master and show up as available nodes only to disappear from the masters' list in a few minutes. On checking the slaves, swarm plugin log still says they're connected to the master. If I shutdown and restart the swarm plugin jar, the slaves again show up for a few minutes and disappear. (They never come back after disappearing unlike Windows slave which come back even if they're briefly missing from the master)

I'm using the latest LTS for Jenkins and v2.0 for swarm plugin.

Can anyone suggest where I should look? There's nothing suspicious in the /logs/ folder for the slave.

Any help is much appreciated.
