[hobbit] Graphs not working on individual views, but working on trends view

[Mark Stoltzfus]

I've done some more digging, and come up with another puzzling piece of information.  Hobbitgraph.sh is returning images, but they are very small.  Here are the apache logs from the two distinct page views:

Disk view (note the size of the file returned, 145 bytes):
10.3.144.37 - - [10/Mar/2010:13:26:52 -0800] "GET /xymon-cgi/hobbitgraph.sh?host=wal-ddbs-01.us.corp.pmigroup.com&service=disk&graph_width=576&graph_height=120&first=1&count=3&disp=wal%2dddbs%2d01%2eus%2ecorp%2epmigroup%2ecom&nostale&color=green&graph=hourly&action=view HTTP/1.1" 200 145

Trends view (a more reasonable file size, 20297 bytes):
10.3.144.37 - - [10/Mar/2010:13:28:26 -0800] "GET /xymon-cgi/hobbitgraph.sh?host=wal-ddbs-01.us.corp.pmigroup.com&service=disk&graph_width=576&graph_height=120&first=1&count=3&disp=wal%2dddbs%2d01%2eus%2ecorp%2epmigroup%2ecom&graph=hourly&action=view HTTP/1.1" 200 20297

Anyone have any ideas?

If it helps any, my graphs are being generated with the same links as
yours (nostale vs no nostales) without issue.

There's probably some other underlying issue.
