CCL: G03 using Linda on an opteron cluster running SLES9

We are having difficulties running Gaussian G03.C01 on our opteron cluster running SuSE Linux Enterprise 9.0. The single processor g03 executable appears to work fine. However, with the Linda executable g03l jobs sporadically die quietly. It appears to always be vibration calculations. The same exact job will ususally complete successfully if resubmitted. Finally, the jobs die even if set to run only on a single processor so Linda itself "shouldn't" be coming into play. All suggestions will be appreciated.
