[isf-wifidog] Wifidog Process Hangs

[Nick Powers]

Hi All,

  Twice over the weekend the wifidog process hung and I had to 'kill
-9' it and then running it again. I am using the following command line
to start my wifidog service: 

'wifidog -f -c /etc/wifidog.conf -d 7' 

Of note I am running this on a Suse 10.3 server (both gateway and
auth). Here is last log information I have for the most recent hung
process:

Also, does anyone have a great way to monitor this process? We use
Nagios and I'm trying to find a nice,clean way to link it with wifidog.

Thanks,

Nick
