Selinux is set to permissive.
Most graphs are working for other tests. Some complicated ones with variable data points. I didn't set those up, but they are working well.

This is probably a sign of invalid rrdctl socket files, as that's what
showgraph is trying to use to communicate with xymond_rrd.
These should be in the TMP/RUN dir on a source compile, named
"rrdctl.<pid>", one for each of the currently running xymond_rrd
processes (usually two,m one for status, one for data). They'll need to
be writable by your apache user at least, and SELinux may require
additional permissions for the sendto if you have it enabled and
enforcing. If you see lots of stale ones, be sure to remove them -- as
showgraph.sh doesn't know what's current, I believe it tries to cycle
through all of them, which could end up in timeouts.
Regardless, premature header ending isn't a desired result no matter
what the situation. Trying to find all cases of this is a longer term
goal for all the CGIs.
