I think you've run into the problem of the /tmp directory being cleaned out whenever your computer reboots. You either need to change the directory that you're storing your Kafka logs to, or change the $TMPTIME environmental variable in /etc/default/rcS which controls how long the tmp files are kept around (time in days).
