However, the next one doesn't: $ mkdir /tmp/foo $ cd /tmp/foo $ for i in `jot 300 1`; do touch $i; done I have a 256Mbytes of swap-backed /tmp configured in /etc/rc.local as follows: $ cat /etc/rc.local mdmfs -p 1777 -s 256M md0 /tmp According to a post on an anonymous BBS in Japan, malloc-backed /tmp doesn't seem to trigger the panic.
