Subject clustered garbage collection
Date Thu, 26 May 2011 11:22:59 GMT
First off, thanks to writers of this great little description of how to do
garbage collection and Fabian for pointing it out.

My next question concerns running garbage collection in a cluster. If had a
number of identical nodes running in a cluster, each of them periodically
running a garbage collection task, where the periods may overlap... say
nodes 1 starts and then in the middle of either the mark or the sweep, node
2 starts it's mark or perhaps even overlaps it's sweep.... what will
the consequences be? Will they "collide", i.e. will their be unexpected
errors (explicit exception based errors) or mis-behaviors (implicit
non-identified errors)?

Of course, the alternative is to guarantee that only one node in the cluster
is responsible for the periodic mark and sweep.

Thanks in advance for any pointers or insights. This community has been
GREAT at responding to questions with very helpful solutions and bug fixes.
