What bridge are you running? You might need the latest bridge software. If it is Informatica or JDE, you should be using the adapter in 6.x.
I have also seen this error has related to ulimit in AIX environments and we have a paramter that you can try adding to your tagent.ini. More information is below. In the future, please contact support for errors to ensure faster response. This forum is not designed to support errors in the product.
AIX only
HOT00464 : AIX Agent not honoring ulimits set from LDAP.
Problem : Customer desires way to make agent work as it did before
HOT00444.
Fix : Added 'ulimitold=y|n' tagent.ini parameter to control whether read
standard AIX limits file or not (default is read file - 'ulimitold=n').
If this does not resolve your issue, please contact support for further help.
