Testing cause for proc_auxv files

I'm determined to find out the source of the files are produced and instead of doing blind test I would like to request help from the community.

If you have tens or hundreds or thousands of files named proc_auxv in the root of internal storage, please help by replying details about your system.

Xposed or not: (and list of modules installed and used)
L-speed or not: (and options enabled)

[or anything else you think is suspicious]

Or if you have any clue do reply too.

Thanks everyone.
