This causes MRTG (in d= aemon mode) to fail all updates. Fine; I restart rrdcached and expect it all to work - but it doesn't. Seem= s that once MRTG has failed to connect to rrdcached once, it never tries ag= ain until you restart. Should MRTG die when a remote update fails? Or should it re-attempt connec= tion to rrdcached? If so, I'm not sure how, as the RRDs Perl module seems = to be the bit to blame for this. Thoughts?
