acknowledgment for a yellow alert doesn't seem to work

[Tom Georgoulias]

Figures, just as I'm about to host a session to show off Hobbit to the 
support team and roll it out into production, I hit a situation that has 
me scratching my head.

I've got an add on script, bb-memory, that is monitoring the memory on 
my linux clients and on one system it is in the yellow state at the 
moment.  A Hobbit alert was generated, it was sent to the appropriate 
email address, yada yada yada.

When I try to use the ack code from the subject line to acknowledge the 
alert, it doesn't work.  Doesn't show up in ~/data/acks/acklog or on the 
web page, and using "!xxxxxx" doesn't have any effect either.  Within 
the same hour, I had a red alert from a different host (disk usage) and 
I was able to acknowledge it successfully.  Thought I'd be clever and 
clean up just enough to make it turn yellow, which it did, and was able 
to ack the yellow alert as well.  SO it didn't have anything to do with 
color states.

Using hobbit 4.0, with the following patches from the list:

bbnet-iponly.patch
hobbit-4.0.1-diskhistlog.patch
eventlog-crash.patch
post-4.0-includes.patch

Any ideas on what to check?
