The server still runs, in contrast to the situation described in my posting from yesterday (MALException:algebra.join,HEAPextend: failed to extend). The other information can be found in this posting as well.
We are working on making MonetDB more robust against allocation failure due to running out of address space with larger (intermediate) data volumes on 32-bit systems, i.e., we try to keep the server alive in such cases (some improvements will be available in the upcoming Nov2009 feature release; more will come later). However, we cannot (easily) lower the address space requirements of MonetDB. They stem from MonetDB's operator-at-a time bulk-processing execution paradigm that MonetDB owns major parts of its performance to.
