Airflow instances with a lot of DAG runs create lots of small log files. The `find` command is able to search for patterns, iterating over and deleting them. However, the old way would use the shell's globbing feature and pass the directories to check for as individual arguments. This may caused an "Argument list too long" error.

this is enough to fix the issue. And find statement for empty folders should be fine

You may commit this change if you want, but I see no difference there. The -name only adds a check which should always be true. Appending the /* should also have no effect, as the -type f check will ensure, we only delete files anyway.
We run this patch internally for quite some time now without any issues.
Deleting around 8k files a day.
