A final plea

We have gotten to the point where the frustration is too much. We are
still suffering from this strange crash with QDNS. It is that typical,
server deafness/crash/quit/just flat out dies problem that we have
mentioned on several occasions. We have tried everything we can think
of. Different machines, different versions of the OS, different
allocations of RAM, reinstall this, reinstall that... You name it.

I have been studying the logs when the crashes occur for some time now,
and have come to the conclusion that QDNS dies during zone transfers. We
thought it might be excessive recursive queries or a combination of both,
but we eliminated that possibility by pointing users to another server
for recursive queries. QDNS always seems to have problems during zone
transfers to secondaries. I know that I have been told that this is not
sufficient enough load to kill the server, but I believe it is, and it
does.

I came to this conclusion because every time QDNS pukes the last thing
that was going on was a zone transfer. And the first thing that is going
on when it "tries" to come back up is a zone transfer. We typically have
to reboot 3 or more times to get the box to come back up after a crash
like this. Also, if we stop/block access from all secondaries doing zone
transfers when we restart the server after a crash, it will come back up
without multiple reboots.

At this point I am lost. The more load this server gets, the less
reliable it becomes. Is there a timeline on the OSX version?
