ORA-12223: TNS:internal limit restriction exceeded Oracle 8i on AIX

I have a site running Oracle 8i running under AIX 4.3 They are using Sage (Tetra) CS/3 with this and are getting the following error

ORA-12223: TNS:internal limit restriction exceeded.

This appears to require tuning of the database/op sys parameters, but I can't establish exactly which parameters/files require amendment. Help!

I suggest you check your sqlnet.log file for any OS errors. The most common cause of this is that some OS resource is low. I would check the swap space.
