I had the same problem (and partially i still have one) ..
So :
1. that "drop messages" message is because of the write errors .. you
can ignore that

2. the problem is with rrdcached .. i tried with making part of group
ganglia, change ownership of rrds to ganglia:rrdcached but had the same
errors ... in the end i had to make the rrds dir 777 and i get rid of errors

3. ganglia web does not function with the rrdcached limited socket so i
had to use the same full socket that gmetad use ... i hope that nothing
bad will happen but i have no other choice...

HTH,
Adrian
