NAV CE 7.6 causing server abends

I work with a global company with approx 500 NetWare servers, both 4.11 and 5.0. We currently are piloting NAV CE 7.6 and have seen 7 of our 4.11 servers suffer hard abends shen attempting to run a scheduled scan. I’m working with Symantec but am wondering if anyone else has seen anything similar.
