This is a just a guess, but an educated one - RHEL3 is using a RedHat 
back port of NPTL which is, how to say it... completly fscked up :-)

If this is really the problem then all you have to do to resolve the 
issue is to add a line with:

export LD_ASSUME_KERNEL=2.4.1

to the init script that runs Asterisk.

For an explanation of what this does look here:

If this does work, you must do the following:

1. Tell me it worked, I'm a curious bastard :-)

2. Call up RedHat support and tell them to  fix their broken 
"Enterprise" distro.


Good luck,
Gilad
