incron - 0.5.12-1 - This program is the "inotify cron" system.  You can use it a similar way as the regular cron. The difference is that the inotify cron handles filesystem events rather than time periods.

# incrond --version
incrond 0.5.12

check.sh is my script, runned by incrontab; let's see, how much zombies incron made:

# ps | grep check.sh | grep -v grep -c
300

And my system is up just for about 16 hours

# uptime
 11:06:09 up 15:54,  load average: 0.00, 0.00, 0.00

fast temporary fix is to downgrade to 0.5.10

wget https://bin.entware.net/mipselsf-k3.4/archive/incron_0.5.10-1_mipsel-3.4.ipk
opkg install incron_0.5.10-1_mipsel-3.4.ipk  --force-downgrade
