Hi All,

i am getting " Too many open files" error when cross compiling chromium on Ubuntu.
This error appears in Bluetooth module /src/device/bluetooth/

I tried several potential solutions like increasing file limit using "ulimit" commands and hanging soft/hard limits using "sudo gedit /etc/systemd/system.conf" but nothing helped.

So i have 2 options:
1.)Resolve this error
OR
2.)  Disable compilation of Bluetooth module, i couldnt find any defconfig or .config kind of file anywhere in code to set flag CONFIG_BT similar to other linux projects

Any pointer is appreciated. TIA
