Hi.  We are running Hobbit v4.2.0 on a Red Hat Ent Linux WS rel 4 server.
We have been running it for about two years without any issues (Great
tool!).  A month and a half ago, the trends graphs stopped graphing.  I
restart Hobbit/Xymon and the graphs start working for a few hours, then
stop.

Looking in the rrd-status.log I do see entries with garbled data

This brings memories of a bug that I fixed a while back, but I
can see that it has only been fixed in the development version -
not in the 4.2.x series.

I think this patch - should work for both 4.2.0 and 4.2.2 -
will fix your problem. I'll add this for 4.2.3.
