I don't know if there are any x86 processors that allow 64 bits of address space yet. AFAIK, they are mostly 48 bit. > http://msdn.microsoft.com/en-us/library/aa366778(v=VS.85).aspx#memory_limits > > Apparently windows limits you to 8TB virtual address space > (ridiculous), so i think you should try one of the following: > * continue using mmap directory, but specify MMapDirectoryFactory > yourself, and specify the maxChunkSize parameter.

Perhaps something like 1G wouldn't impact performance, but could help avoid OOM due to fragmentation? -Yonik http://www.lucidimagination.com
