Something strange happened on my server. It seems that a cookie expired after only 9 minutes (or less). I've included the pertinent info below. What would cause this behavior?

2005-04-07 16:38:06 Cookie 753059 not found, dropping ack
After the ack failed, I ran the following (thanks for the patch, Henrik):
./bb 127.0.0.1 "hobbitdboard host=sundeigh.deightime.net test=meta fields=hostname,testname,cookie" sundeigh.deightime.net|meta|615614
date (run right after the above bb command)

Could you try the attached patch ? If causes hobbitd to log if it receives an ack-message that is discarded because the cookie was not valid.
Patch seems to work.
I have a yellow alert on a system.
Check the cookie: -bash-2.05b$ ~/hobbit/server/bin/bb 127.0.0.1 "hobbitdboard host=radm200p.nandomedia.com test=disk fields=hostname,testname,cookie" radm200p.nandomedia.com|disk|406429
Wait a while, then check again: -bash-2.05b$ ~/hobbit/server/bin/bb 127.0.0.1 "hobbitdboard host=radm200p.nandomedia.com test=disk fields=hostname,testname,cookie" radm200p.nandomedia.com|disk|712535
Use the old cookie to try and ack the alert, then check hobbitd.log:
bash-2.05b$ tail hobbitd.log 2005-04-06 14:55:48 Setup complete 2005-04-06 15:01:33 Setup complete 2005-04-07 13:21:55 Setup complete 2005-04-07 13:36:53 Cookie 406429 not found, dropping ack
Stale cookie didn't work, event was logged.
So now the real issue for me is how to use this piece of info about cookie lifespans when I put Hobbit into production. I don't want the support folks to have to log into my hobbit server and check for the latest cookie value before acknowledging an alert. I've also got a range of time & repeat delays for my alerts, depending on what system parameter is being measured, and I'd hate to have to use <30 mins across the board.
