Panda robot oscillates in gazebo after spawning

Hello, I'm following [ROS_Control tutorial](http://gazebosim.org/tutorials/?tut=ros_control) and adapting all the instructions for panda robot. I have generated the Gazebo compatible of URDF of panda from Moveit setup assistance and i'm editing it as per the ROS_Control_tutorial. Once the robot is spawned in gazebo it oscillates around its joint1 automatically(it moves back and forth and then rests on ground).   I have already tried below things but couldn't solve the issue:- 1. Set p-i-d gains to very low value and manipulated them accordingly 2. i have tried increasing the mass and inertial values in URDF file. Below is the URDF file which i'm using:- transmission_interface/SimpleTransmissionhardware_interface/EffortJointInterface50hardware_interface/EffortJointInterfacetransmission_interface/SimpleTransmissionhardware_interface/EffortJointInterface50hardware_interface/EffortJointInterfacetransmission_interface/SimpleTransmissionhardware_interface/EffortJointInterface50hardware_interface/EffortJointInterfacetransmission_interface/SimpleTransmissionhardware_interface/EffortJointInterface50hardware_interface/EffortJointInterface/panda any suggestions for this scenario! Thank you for reading.
