10-11pm RRD gap in graphs (4.1.1)

I have an odd issue...

From around 10pm at night to around 11pm (EST) I have a gap in my CPU and Processes/Users graphs.  

I haven't seen any reasons in the hobbit logs.  Other RRD graphs are fine (disk, vmstat, etc)

This is not just one night, but every night.  I am using the hobbit client on the hobbit server, and hobbit client on another linux box (both are CentOS 4).

Has anyone else seen this?  What is significant about CPU, Proc/Users graphs?

Thanks

I actually get the same thing, but it happens between 5:30 and 6:30 every
day.

It's a bug in the client handler. The reason why it happens for one hour
every day is that the "uptime" output is different for that hour. Most
of the time, it looks like

 08:26:57 up 4 days, 10:22,  3 users,  load average: 0.01, 0.10, 0.06

but for one hour each day - starting N*24 hours after it was booted - it will be

 08:26:57 up 7 days, 13 mins,  3 users,  load average: 0.01, 0.10, 0.06

which the 4.1.1 version of hobbitd_client fails to recognize.


I really need to get 4.1.2 finished ...
