failed: out of memory

[Tim Krzywonos]

Have you tried an rndc flush?  You can also dump the contents of the 
cache to find the (approximate) size of the cache.  If related to cache, 
you can tweak parameters to cache, most namely max-cache-size.  IIRC, 
the cache doesn't have a size limit by default.
