9.5.0-P2 and socket: too many open file descriptors

[Ejaz]

Dear all, 

How can I increase  the amount of file descriptors available in my solaris 10 (x86),  Is there some setting in /etc/system that I can do this ? 

I have following entries in my logfiles. So my question is do I recompile bind BIND 9.5.1b1?? , as I red so many emails saying that this version has stable 


Aug 17 10:38:43 ns1 named[2822]: [ID 873579 daemon.error] socket: too many open file descriptors
Aug 17 10:38:48 ns1 last message repeated 356 times
Aug 17 10:38:50 ns1 named[2822]: [ID 873579 daemon.error] socket: too many open file descriptors

Even i dont know this problem from the bind or O/S, any clue will be great for me. thanks  in advance. 

My Environment is 

Solaris 10x86
Bind 9.5.0-P2


Regards
Ejaz

To answer my own question I recompiled named with some diagnostics and find 
out that 1024 is still the FD limit:

13-Aug-2008 14:07:03.480 general: error: too many open file descriptors: 1024

I followed the example and ran configure like this:

STD_CDEFINES='-DFD_SETSIZE92' ./configure

and found this in the log:

config.log:STD_CDEFINES='-DFD_SETSIZE92'

What am I doing wrong?

Thanks,

ds
