In this recursive server (2xPIII, W2KSP4, 1G RAM) which crashed 5 hours ago named now has named using 138M of RAM, 2325 handles and 9 threads.

The caching-only server (2xXeon dualcore, W2K3, 4G) where I switched from 9.5.1b1 to 9.5.0-P2 today, just crashed again. After restart the named used 28M RAM, 270 handles and 14 threads. Now after only 5 minutes it is 35 megs, 690 handles and 14 threads and both the memory consumption and handles are growing every cycle.
