Router: ASUS RT-N10+ (B1) (Ralink) build: r27506
One of the cron jobs I have is this:
*/10 * * * * root wget -T 30 -qO - http://www.unotelly.com/unodns/auto_auth/hash_update/updateip.php?user_hash=(myhashgoeshere)
I often get zombie process in ps:
1499 root 0 Z [sh]
Because I also have DDNS running, by looking at DDNS log I've noticed that every time external IP changes I get a zombie process, this can be 10-20 zombie processes in just one night (the ISP seems to have a timeout and the IP tends to change a lot when there are no computers running on the network).
I don't know if this is related but cron seems to be running as an orphan for some reason:
Jan 1 00:01:43 petinga user.info syslog: cron : cron daemon successfully started Jan 1 00:01:43 petinga cron.info cron: (CRON) STARTUP (fork ok) Jan 1 00:01:43 petinga cron.info cron: (crontabs) ORPHAN (no passwd entry)
So, it's either cron + wget (or inadyn?) that is causing these zombie processes, you can see I already added a timeout to wget but that doesn't seem to make a difference.
