Solution
The following work-arounds can be used to overcome this issue
1) Increase the timeout in XSCT.

Create a file with name .xsdbrc in the $HOME directory

Add the line below in the .xsdbrc file

configparams-sdk-launch-timeout 180
2) Clean up using the following commands:

 rm -rf ~/.Xil

rm -rf ~/.Xilinx

Note: This error could be due to a resource constraint on the PC.
The minimum configuration required for PetaLinux tool installation is 8 cores and 8GB RAM (This is not corrected in 2016.4-2017.2 (UG1144) documentation).
Ideally one project should be built at a time.
If you want to run projects in parallel, set parallel threads and configure execution in petalinux-config->Yocto Settings to lower values which match your system configuration.
