So I'd recall. I found some thread where people are having the same memory error message. Some using MicroB, some using Modest and no-one seems to have a clue what is causing this. I've now noticed that the top may show low memory even if I'm not running any programs at all. I think Qspot isn't responsible for this behaviour it just happens to "cross the line" for the error message in my case. If only I could know what is causing this...
