Sorry again for the long delay, I've got other work to do, and our 9.4 servers work fine (at least on FreeBSD 6, though, see the other -performance- problem)...

Okay, then please try this patch with '-n 1' (note: this patch doesn't
contain the memory statistics hack via the HTTP interface, but I don't
we don't need it for this test).

Hmm, then the mutex locks dynamically generated are also irrelevant.

I've also tried to reproduce the problem in a similar environment
(BIND 9.5.0b1 with threads on FreeBSD 7.0RC1/AMD64, cache-only
configuration, using a real query sample), unsuccessfully.  One
significant difference is that I disabled SMP in the kernel (it was
very unstable with the SMP support for some unknown reason), but I
doubt this is the key for the difference of the named behavior.
I don't know why am I the only one to see this.

BTW, is this reproduceable on FreeBSD 6.x?  If so, then I'd like to
see what happens if you specify some small value of datasize
(e.g. 512MB) and have named abort when malloc() fails with the "X"
_malloc_options.  (This option doesn't seem to work for FreeBSD 7.x,
at least at the moment).
Yes, it's the same, even when there is a different (libpthreads, KSE) threading library is in use.
I've recompiled named with the following in main():
./work/bind-9.5.0b2/bin/named/main.c:   _malloc_options="X";

And set cache-size to 32MB.

At:
21664 bind        4  20    0   819M   819M kserel 0   5:32  0.00% named.950
I pressed a CTRL-C:
mem.c:1114: REQUIRE((((ctx) != ((void *)0)) && (((const isc__magic_t *)(ctx))->magic == ((('M') << 24 | ('e') << 16 | ('m') << 8 | ('C')))))) failed.

Some other questions:
- can we see your named.conf?  If you specify non-default
  configuration options, that might be the reason for, or related to,
  this problem.
Of course (see at the end).

- does your named produce lot of log messages?  If so, it might also
  be a reason (simply because it relies on standard libraries).
grep named ns20080403.log | wc -l
1930006
For today (17 hours and 18 minutes of logs).
Is this a lot?

Config (normally max-cache-size is about 2400M):
-hmm I haven't tried to change cleaning-interval, it was needed because the default cache housekeeping effectively stopped the ns during the cleanup-

options {
       directory "/etc/bind";
       tcp-clients 256;
       recursive-clients 8192;
       max-cache-size 32M;
