Bind is hanging on CentOS 4.4

Here is the output from ps -eLf

ps -eLf | grep named

I rebuild named with threads disabled and I still hand a hang afterward.

The implementation of ps has a lot to do with whether you see threads.

You might try:
To get info about threads:
   ps -eLf
   ps axms

I have decided to rebuild named with threads disabled. I will update you on
the results. I am hoping that will remedy the issue.

Thanks for your support.

It depends on the ps implementation.  To be sure, you should start
named with the -g command line option and see initial log messages
on stderr.  If you see something like this:
26-May-2009 12:11:39.619 found 1 CPU, using 1 worker thread

threads are enabled.  If the threads are enabled, the best way to
eliminate the possibility of dead lock is to rebuild named
--disable-threads.  If you cannot do it, maybe you want to try
invoking named with the '-n 1' command line option.

p.s. if you don't mind, please cc follow up messages to the bind-users
list.  Then you can expect more help from others.   I'm just back from
vacation with so many email backlogs and my responses may be overly
delayed.
