However, if using Spur, you can try to change the young space size, which also changes the remembered table size and might fix your problem. To do so you can do:
> Smalltalk vm parameterAt: 45 put: (Smalltalk vm parameterAt: 44) * 4. And then restart the image.

Normally in Spur if the remembered table grows too big a tenure to shrink the remembered table happens, so that error should not happen. Eliot is currently moving to another place, so he might be busy. If he is available to answer, I guess he will have a look, if he is not, I can have a look today or thursday. However I am not interested in fixing pre-Spur VMs.
I should be able to look at this next week. It is an important bug that I want to look at ASAP.
