[AshishKumar Mishra]

Hi Members ,

Can team members please let me know the solution & what is causing the
below mentioned error ?
( I am having around 128GB of disk space still left , hence don't think
that space is the issue here )

~/Documents/linux-foundation-projects/yocto/poky/build (slef-bsp) : bitbake
-vn virtual/kernel
ERROR: No space left on device or exceeds fs.inotify.max_user_watches?
