[hobbit] Network tests stopped graphing

Also, I was wondering if this may have any bearing on the situation:

16677 hobbit    25   0  2896 1328  604 R 92.6  0.3   1:21.78

As you can see, my hobbitd_client frequently goes up to 98 percent and
normally does not go any lower than 60 percent.

Could this be causing some type of bottleneck that is causing problems
with the graphing?

I was using an old bb command from my previous bb installation, I found
the correct one and when I use it all it gives me is about 7 lines of
blank space.  The rrd files seem to be updating, but I am getting an
error in my rrd-status.log file

2006-01-06 07:24:20 RRD error updating
/usr/local/hobbit/data/rrd/HOSTNAME/tcp.ftp.rrd from
illegal attempt to update using time 1136553860 when last update time is
1136553860 (minimum one second step)

And this keeps repeating in the past

The messages that are coming through using the bbcmd listener look like:
status HOSTNAME.memory green Fri Jan  6 08:26:06 CST 2006 - Memory OK
   Memory              Used       Total  Percentage

&green Swap                 85M       1664M          5%

I don't know which "bb" command you're using, but that error message 
does not look like anything that I wrote in the Hobbit "bb" utility.
In fact, I checked and
   henrik at osiris:~/hobbit$ grep -i "can.t open" */*.c
finds no matches in my Hobbit sources.

A connect-error should give you either 
   "connect to bbd failed - <OS errortext>" 
   "Could not connect to bbd@<some more text>"

I think those two observations are un-related. Are your memory RRD files
being updated ? If not, are there any errors in the rrd-status.log file?
If you run (as the hobbit user) 
   bbcmd hobbitd_channel --channel=status grep -A 10 "^@@.*|memory|"
do any memory status updates appear for these hosts, and what do they
look like ?
