This is another limit than the out of memory error. Too many references
from old objects to young objects. The limit cannot be changed directly
from the image. 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.*
TUNING NEW SPACE SIZE for more info about that.
If you are using Spur, could you send us the image (if it is 500Mb could
you put it to download on dropbox or something like that ?) ? That way we
can reproduce and see what is possible. 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.
