linux - Random empty files called "file*" are created on /tmp

I have two RHEL 6.10 servers where /tmp is constantly being filled up with thousands of files with the following names

-rw-rw-r--. 1 root    root        0 Feb 22 17:30 fileoQ1gE0
-rw-rw-r--. 1 root    root        0 Feb 22 17:31 fileTFa0e7

-rw-rw-r--. 1 root    root        0 Feb 22 17:42 fileBP8HL0

-rw-rw-r--. 1 root    root        0 Feb 22 17:49 fileN1VVJU

-rw-rw-r--. 1 root    root        0 Feb 22 17:50 fileHO9fll
-rw-rw-r--. 1 root    root        0 Feb 22 17:51 filejEj1Rq
-rw-rw-r--. 1 root    root        0 Feb 22 17:52 fileMPnCWJ

Root's crontab doesn't have anything so, is there any way to know what process is creating files here? Even though they're 0 bytes it is bothering me since I just don't know why they're created.

Answer

Enable auditd and write some rules watching write-type permissions to this directory.

-w /tmp -p w -k tmp
