If it's only doing a long GC pause once a week, I think I'd prefer to go
ahead and let it do the long GC pause.  It would be less of an
interruption than restarting Solr.

Or is it getting into a mode after several days where it goes crazy and
has a lot of major GC storms?  If that's the case, is it happening even
with the GC tuning parameters I gave you before?  I run my Solr
instances for months without issues.  Right now, my production Solr
instances have been running for 25 days.
