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?
