Subject Re: Slave index size growing fast
Date Fri, 23 Mar 2012 14:48:50 GMT
What version of Solr and what operating system?

But regardless, this shouldn't be happening. Indexes can
temporarily double in size, but any extras should be
cleaned up relatively soon.

On the master, what's the total size of the <solr home>/data directory?
I'm a little suspicious of the <backupAfter> on your master, but I
don't think that's the root of your problem....

Are you recreating the index on the master (by deleting the
index directory and starting over)?

This is unusual, and I suspect it's something odd in your configuration,
but I confess I'm at a loss as to what.
