BIND - out of memory

[Jan Arild Lindstrøm]

Hi,

I am running ResPerf from Nominum against BIND 9.6.1b1, and I get a lot of:

What does "database: adb: .. out of memory" mean?
What does "query-errors: fetch completed at ... out of memory/success" mean?

Solaris 10 on a Sun T5140 with 6 cores/96 threads and 16GB of memory: 
	SunOS xxx.xxx.xx 5.10 Generic_138888-01 sun4v sparc SUNW,T5140 Solaris

The named process takes only 170MB:
	Memory: 16G phys mem, 11G free mem, 4104M total swap, 4104M free swap
	 19563 named     99  59    0  171M  169M sleep    1:35  0.00% named

BIND 9.4.3 on the same server (running at the same time as testing 9.6.1b1):
	 10186 named     99  54    0 2990M 2989M cpu/66 5438.0  3.84% named

I tried:
	datasize unlimited;
	stacksize unlimited;
	max-cache-size unlimited;

But it had no effect, I still get just as many "out of memory" lines when running ResPerf.
	resperf -d queryfile-example-3million -e -s <IP address> -m 10000

Plimit reports (on the named process):
	resource              current         maximum
	time(seconds)         unlimited       unlimited
	file(blocks)          unlimited       unlimited
	data(kbytes)          unlimited       unlimited
	stack(kbytes)         unlimited       unlimited
	coredump(blocks)      unlimited       unlimited
	nofiles(descriptors)  unlimited       unlimited
	vmemory(kbytes)       unlimited       unlimited

Any hints on what these "out of memory" messages mean would be appreciated.

Thanks
