//---------------------------------------------------------------------------------------------------------------- Because of out of memory issue every day I need to restart Jenkins server to make it up, this has became really a pain in neck, anyone has any idea on how I can go away with this issue any configuration I need to change under my Slave m/c Slave Lunch Method is “Launch Slave via execution of command on Master”. Any help in this regard is highly appreciated.
