This probably comes from the stat() system call.
It can happen if you use an XFS with inode64 option and 32-bit apps for example, and it'll happen with any 32-bit app (try gcc).

What is your filesystem? What is your kernel ('uname -mrsp')?
Are you running a 32-bit or 64-bit ClamAV? ('file /usr/bin/clamscan' will tell you)

Does 'stat myfilename' work?

I don't think its the file's size the problem, but rather its inode.
Use a 64-bit clamscan/clamd if your filesystem uses 64-bit inodes.

If you scan something outside the limits you don't get an error, you get an OK.
