I cheered a bit too early :
16-Jul-2008 15:37:48.283 loading configuration from
'/etc/bind/named.conf'
16-Jul-2008 15:37:48.315 reloading configuration failed: too many open
files
Which is strange because ;
root at ns1:~# plimit 7323
7323: /sbin/named -u bind
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) 32768 32768
vmemory(kbytes) unlimited unlimited
root at ns1:~# ps -ef | grep bind
root 9097 18895 0 15:41:58 pts/2 0:00 grep bind
bind 7323 1 26 07:42:35 ? 517:08 /sbin/named -u bind
root at ns1:~# plimit 7323
7323: /sbin/named -u bind
resource current maximum
time(seconds) unlimited unlimited

coredump(blocks) unlimited unlimited
nofiles(descriptors) 32768 32768
vmemory(kbytes) unlimited unlimited
root at ns1:~# lsof -p 7323 | wc -l
600
I'll dig into it some more.
