So the server is complaining that it already has a server by that name. When the slave job is down, does the Server still regard it as up? Maybe Jenkins hasn't noticed yet (there's a 4-minute "ping timeout" involved, so it might not have).
I have a cron job that runs every five minutes, looking for the slave job with the help of "ps". When it can't find it, it fires off "nohup bash launchSlave.sh &". The launchSlave.sh job sets some environment variables and launches "java -jar slave.jar -jnlpUrl ...". --Rob From: jenkinsci-users@googlegroups.com [mailto:jenkinsci-users@googlegroups.com] On Behalf Of Stuart Green Sent: Tuesday, May 28, 2013 10:03 AM To: jenkinsci-users@googlegroups.com Subject: Jenkins Linux Slave fails to connect to Jenkins master - JLNP Java Web Start Hello.. This is getting to be a bit of a pain, it seems to happen every time we reboot the linux slave, but does not happen when we reboot the windows slave that we have. We are on Jenkins ver. 1.515 so the fix in 1.398(off the top of my head) is definitely there.
