On Googling, I found a lot of people got this a few years ago, but not really recently. Anyway, we installed new hardware (w/ lots of memory) and now see this message about 4 times a week.
I've installed the latest GuiXT (currently 2012 Q1 V3) and the latest SapGui (7.20 patch 10) but still get the error. I've tried different combinations of earlier versions (randomly) but still see it. I'm thinking of going to an much earlier version, but those all had various issues too.
The exact error is "Not enough memory - please increase virtual memory" w/ a title like "get memory: length=2123776 file=C:Sourcegrlib.." On Windows 7.
Thanks for any help
