error: socket: too many open file

[jyoung at trytel.com]

Hi,

I am new to the forum, i didnt see if anyone else had this problem.
So here
it is.

I upgraded from BIND 9.2.4 to 9.5.0-P1 on a Solaris 10 SPARC server.

Since doing so, my log file is filling up with these.

08-Sep-2008 16:06:41.202 general: error: socket: too many open file

I believe i understand the problem, i just can't seem to fix it.

The default 'open files' descriptors was 256.  I up'd it to 4096.
[root at ns1-3 /var/log]# ulimit -a
core file size        (blocks, -c) unlimited
data seg size         (kbytes, -d) unlimited
file size             (blocks, -f) unlimited
open files                    (-n) 4096
pipe size          (512 bytes, -p) 10
stack size            (kbytes, -s) 8192
cpu time             (seconds, -t) unlimited
max user processes            (-u) 29995
virtual memory        (kbytes, -v) unlimited

Restarted Server and named, and still seeing these errors.

So I tried recompiling BIND with:
STD_CDEFINES='-DFD_SETSIZE=4096' ./configure --without-openssl
make

But still didn't work.

Using LSOF, i can see it has open 1023 UDP ports.

Any advice?
