We have a custom script that just goes out and grabs a status from a few web sites for a product. It seems to work fine. When we go to the history page for the test, all the change of status is there as you would expect. But when you scroll down and select a colored ball under the status column some of them work and some do not. The ones that do not work generate a browser error that states: File Not Found Firefox can't find the file at https://XXXXXXX/xymon-cgi/bb-histlog.sh?HOST=XXXXXXX&SERVICE=customtest&TIME....

The data file is in the histlogs directory and has the correct name. The data in the file is correct. So we copied the line that says "Client data ID 1234567890" in a history file that displays correctly and replaced the line in a file that does not display correctly. It now shows up fine with the correct data. So maybe the "Client data ID" line is the problem. Replace the line with a known good one and all is well. Checked perms and they seem fine. The httpd error log generates the following when a status is selected that does not display correctly:

[Tue Jun 23 12:31:14 2009] [error] [client xxx.xxx.xxx.xxx] Premature end of script headers: bb-histlog.sh, referer: https://XXXXXX/xymon-cgi/bb-hist.sh?HISTFILE=XXXXXX.customtest&ENTRIES=50&IP...

Error is not generated when a status is selected that displayed correctly.

Anyone have an idea on how to fix this? Not really sure how "Client data ID" line is being used or generated. If in fact that is the issue.
