Fatal error: shared memory will conflict with server

Explanation
The shared-memory segment allocated to onpload
is located below the shared memory segment of the server, and the
size needed to run the job would cause the onpload shared memory to
overlap the shared memory of the server.

User response
Reduce the size and number of buffers allocated
to onpload on $INFORMIXDIR/etc/plconfig or %INFORMIXDIR%\etc\plconfig,
or increase the start address for the shared memory location of the
server.
