Hi,

I run into the same problem with xymon 4.3.0-0.beta2 on Red Hat
Enterprise Linux Server release 5.4

It works most of the time with Firefox 3.6.8, but not with Internet
Explorer 6

Error message in Internet Explorer: Premature end of script headers:
bb-histlog.sh

# dmesg | tail -1
hobbitsvc.cgi[10759] general protection rip:3226471d71 rsp:7fffd27264e0
error:0
