Sorry Jose, but that is not an issue. The 12 Gb file is copied to the NAS
without a problem and completely the same as the original. I don't know how
Windows XP handles NAS-devices (Freecom Network Drive, attached by using
Explorer - Map Network Drive) and the way they are formatted, but if the
FAT32 would be a problem, then it shouldn't be possible to have a file larger
than 4 Gb on the NAS. True?


Although that's true, what Jose says is correct. You can not have a
FAT32 file larger than 4GB. So something must be wrong with what you
are saying here.


Any other suggestions?

I'm using SyncBackSE to backup my harddisk data (NTFS) to a network attached
harddrive (FAT32). Among this data is a large 12 Gb file. What happens during
backup (I think only during backup of this large file, but I'm not sure) is
that the page pool / kernel memory gets exhausted, which after a few backups
leads to my PC completely freezing. I've run PoolMon.exe to find out which
process allocates memory without freeing it, but the only thing I know so far
is that the pooltag responsible for the memory leak is 'NXFS'. I did not
manage to find out which process is using this pooltag, so I'm stuck in
finding out which process is causing the memory leak. Is there anyone who
experienced the same problem or knows which process uses the 'NXFS' pooltag?
This would help me in my quest to find a solution for this problem.

Before you start looking at memory leaks, you need to take into
account the maximum size of a file on a FAT32 volume:

You cannot create a file larger than (2^32)-1 bytes (this is one byte
less than 4 GB) on a FAT32 partition.

You could consider switching the backup volume to NTFS where the file
limit is only limited by the volume size.
