UPPD Batches Error with ORA-06512: at "APPS.PJI_FM_PLAN_MAINT_PVT", line 13026

Hello,

We schedule PRC: Launch Update Project Performance Data every evening, and some batches regularly error with the following log.  Some evenings none error, and other evenings, more than one error.   The batch usually goes through the next time, or the time after.  If we resubmit the batch individually, I have never observed one to fail.  We would have a lot of difficulty with an SR because we cannot control the replication of the error.  Are you familar with this error, and is there a resolution for it? 

Thank you, Kevin
