AV Full scan causing memory exhaustion

Anyone else experiencing a memory leak issue during full AV scans? I have 6 Windows servers in my environment that during a full scan, 15-20 minutes into the scan, commit bytes for the epsecurityservice process start creeping up and soon uses all available virtual memory, until the server is unresponsive and must be hard reset. We are running latest version of the scanner/definitions. Windows are patched, 2012 to 2019 versions. Windows Defender is disabled. One server is a simple file server and the rest are SQL\IIS. I have been working with support for longer than a month, sending logs and process dumps, running scans with troubleshooting command switches, and screenshots to no avail.

Any ideas?
