Has anyone gotten random failures when trying to build a full index in Elastic Search?

We run Elastic Search nightly (through a scheduled jobset) to create our eProcurement (full index) indexes for searching items.  The jobset includes the following search definitions:  1) EP_PV_EXPRESSITEMS_SD, 2) EP_PV_MASTERITEMVENDOR_SD and 3) EP_PV_MASTERITEM_SD.  Periodically, PTSF_GENFEED will go to No Success but the error message given is not real useful:  Process xxxxx ABENDED at Step PTSF_GENFEED ES_STAT Step01 (PeopleCode) -- RC = 24 (108,524).  This periodic abend always occurs with the EP_PV_MASTERITEMVENDOR_SD search definition of the jobset.  After the abend occurs, our solution is to just run another instance of the jobset, which then usually goes to Success.
