Sorry I just noticed the cron. It is indeed /usr/lib/php

If that is the case, then what are these in /home/xxx/tmp?

Got the same issue with this one

Other than having to delete them using

# Remove tmp session files over one day old
find /home/user/tmp -type f -name 'sess_*' -mtime +1 -delete

How to prevent this in the first place?
