cannot start gmond. recompiling the ganglia package and installing ganglia and ganglia-gmond fixed the issue.
Created attachment 337111 [details] fortify backtrace attaching the report. code has no issues, so must be bad compilation. *** buffer overflow detected ***: gmond terminated
Looking in to it, I don't have a rawhide install handy at the moment so it might take a few hours.
ganglia-3.1.2-3.fc11 has been build and fixes the problem (at least in my test machine). I am not sure how gcc/glibc caused the problem in the previous build since I don't see any obvious bugfixes there that could have caused it :(
