Description of problem:
we have two boxes which run a custom application.  both boxes have the same kernel-2.4.21-27.0.2.ELsmp.  one of them is spewing errors into /var/log/messages as follows:

May  2 17:08:54 sblah kernrl:  (see the NOTES section of 'man 2 wait'). Workaround activated.

i cannot determine why one has the errors and the other does not.  any input would be greatly appreciated.

Steps to Reproduce:
1. run our application on box b


Actual Results:  same errors.
