this is definitely a permission related issue. Please try adding -o uid=xxx,gid=yyy (where xxx and yyy are the uid and gid numbers of 'clamav' respectively) to your mount command or to /etc/fstab and let us know if this fixes the problem.

Another solution would be creating a new directory /mnt/memory/clamav with proper permissions and then pointing clamav to this directory instead of /mnt/memory.

The strace snippet was too short to say what's the reason for them but for sure it's not a buggy RAM :-)

Yes, it is

Usually the proper way to specify the owner and group of the root of the fs is to use the gid=xxx and uid=yyy options.

It's definitely not a space issue (empty dirs don't take too much really ;-)), however you should make the ram tempdir big enough to have clamav properly handle large archives or multiple files by concurrent threads, etc. but that's a different story.
