Problem with restarting chilli 1.0.12 - redir.c: 982: 28 (No space left on device) msgget() failed

[Johan Meiring]

Hi,

I have a problem with "restarting" coova-chilli.
This is completely reproducable.

Details as follows:

Running coova-chilli 1.0.12 on openwrt kamikaze 8.09
(somewhere between rc1 and final - r14038)

I have a cron script that checks if chilli is running every minute, and
starts it if not.

When the radius server dies for some reason, chilli eventually dies.
(expected?)

After a while (unsure if it is the first restart after chilli dies)
chilli does not want to start anymore (i.e. crashes on startup).

A simple reboot of the router resolves the problem.  This happens on
both Linksys and Nanostation devices.

logread as follows......

At this point I firewall off the radius server (simulating radius
death) and go home.  The next morning logread shows the following
