[mrtg-developers] Running with rrdcached

I've been running MRTG with rrdcached, and just had rrdcached lock up (out of memory - seems to have a memory leak somewhere).  This causes MRTG (in daemon mode) to fail all updates.

Fine; I restart rrdcached and expect it all to work - but it doesn't.  Seems that once MRTG has failed to connect to rrdcached once, it never tries again until you restart.

Should MRTG die when a remote update fails?  Or should it re-attempt connection to rrdcached?  If so, I'm not sure how, as the RRDs Perl module seems to be the bit to blame for this.
