A family of Microsoft relational database management systems designed for ease of use.
I have the same problem, or perhaps only a similar problem. The Access program reports "out of memory" but there seems to be plenty of memory available. Windows reports 5% memory use - this is a machine with tons of memory. Access.mdb is linking via ODBC to both local and remote SQL Server instances. Popup message reports "Out of Memory".
Control/break at the error message brings up the "continue/debug" option. When I choose debug, I get another popup message that says "Unexpected error; quitting" with an OK button and a Help button. The Okay button makes the message go away but the program does not quit. It's not doing anything productive, either, I think it's frozen. Task Manager reports 340 MB memory in use by this instance of Access.
This is happening on a Windows Server 2016 VM with 368 GB RAM, using Microsoft 365 Apps for business, version 2211, build 15831.20190 Current Channel. Problem just started this week after an update. Program launched at 7:30 this morning and around 1:15 the error popped up. Kill the job, restart it and it's okay for at least several hours. Has happened 2 days in a row.
