> It seems like mmapdirectory doesnt handle concurrency
> this works fine: http://pastebin.com/EQx0L23K
> This:http://pastebin.com/ay6B2Krp (note that the only diff is, that i changed the FsDirectory.Open(newDirInfo) to new MMapDirectory(newDirinfo) in line 12 )
> fails with exception:
> {System.ArgumentOutOfRangeException: Index was out of range. Must be non-2negative and less than the size of the collection.
> Full exception here: http://pastebin.com/erZTxH3d
> If in the second code example I set the concurrentTaskCount to 1, everything is just fine.
> Looks like a concurrency bug for me. Am I missing something?
> T
> Edit: I attached to content of the newMMap folder, after the index is created
