[smokeping-users] 500 Error all of a sudden..

[B. Cook]

Not that it should matter, but I have been running smokeping on this 
machine for over 45+ days on lighttpd and FreeBSD 7.2 (amd64).

Yesterday someone told me smokeping.cgi gave a 500 error, (they were 
right) and as far as I can see I can not find a problem.

if I run ./smokeping.cgi it does produce html output.

thinking for some odd reason there might be something up w/ lighttpd; i 
quickly compiled thttpd.  It to produces a white screen.

I just ran a rebuild of smokeping with portmaster, and same results.

(software versions)

smokeping-2.4.2_1   Latency logging and graphing system

This is perl, v5.10.0 built for amd64-freebsd
