Hi,

I am trying to backup data from a ntfs partition and the system allways 
panics. The backup command is:

$ tar -cf - DATA | ssh a@b "cat > DATA.tar"

The ntfs partition is mounted on directory DATA, it's size is about 
47GB. The DATA.tar file on the other computer is is at the time of panic 
also about 47GB, but the archive isn't complete.

Approximate backtrace:
panic: malloc: out of space in kmem_map
cpu_Debugger
panic
malloc
ntfs_attrtontvattr
ntfs_loadntnode
ntfs_findvattr
ntfs_ntvattrget
ntfs_readattr
ntfs_read
VOP_READ
vn_read
dofileread
sys_read
syscall_plain

It's i386 NetBSD-3.0 with slightly modified GENERIC kernel. What could 
be wrong? Should I collect more information as suggested here:

Thanks,
