[rvm-research] Bug: Error allocating contiguous chunks

There is some error when growing discontiguous space (stack trace below).
This error appears to be timing dependent and does not always occur. On my
system, it seems to happen on about every 1 out of 120 runs of the dacapo
luindex benchmark. This occurs on both jikesrvm-3.1.3

The command line was:

rvm -Xmx300m -X:gc:sanityCheck=false -X:gc:verbose=0 -jar
dacapo-9.12-bach.jar luindex

The RVM was configured with BaseBasMarkSweep.

I've already opened an issue for this:
https://jira.codehaus.org/browse/RVM-1069

Does any one know if this is the same error as
http://jira.codehaus.org/browse/RVM-1008 ?

Also looks like this one that was already closed;

http://jira.codehaus.org/browse/RVM-662


Is there a way to work around this? Increase the heap size (altough 300m
seems quite adequate for luindex)?
