Hi Tom,

Not sure, but are you migrating from a SuperServer to a SuperClassic ?
If yes, i felt on the same problem.
You're getting out of system resources.
You should lower the number of PageBuffers allocated for each connection
(in SuperServer, the cache is shared not in SC).
It should be between 128 to 512 PageBuffers according to your
OS/Resources/Nb of client.

Greg.
