Bulk optimize – nothing happen

HI,

I have 2037 images in the Media Library have been selected (1986 unoptimized), with 11256 resizes (10953 unoptimized).
Previously optimized images will be skipped by default.
Pls. screenshot below,

When I try to bulk optimize I got this result
Screentshot, http://quick-markup.com/p/53606780e1d1e
Pastebin, http://pastebin.com/a17jLgK7

unoptimized images remains as unoptimized.

Thanks in advance.
