wget crashed while using -c opt

I downloaded directory with few files, one of them was 18G, then I interruped wget download. After a while when my inet connection get restored I wanted to continue to download missing files so I typed wget with -c opt.

Wget was checking previously downloaded files and while checking file with size 18G it crashed. Strace output is bellow. Do you have any idea?

Thanks

Strace output:

The file is already fully retrieved; nothing to do.
