Shared Memory File Problem

[CharlesNagy]

We have upgraded Oracle to version 9 and Datastage from V6 to 7.5.2, and a job that used to work, now has the error:

ds_ipcopen() - shared memory file /tmp/PRODACHD.AchMajErpExtrCommLig..RGL_1-RGL_2 is wrong size

The jobs name is AchMajErpExtrCommLig, and RGL_1 - RGL_2 are transformers in the job. Unfortunately, I do not have access to the environment to run the job to debug, so am unable to provide more information.

Would appreciate if anyone can point me in the right direction.
