Bitcoin client 0.4.1.1 stuck at block 176947 Bitcoin client stuck. Tried to rebuild whole blockchain, but it went up to that number and got stuck again. 

Here's a screenshot: http://vvcap.net/db/2IR75OWyJj5AsUW7eo_i.htp

Any suggestions?
I just downloaded version 4.4.1.1 to try to reproduce your problem, but couldn't.  Here's the beginning, and relevant mid-section of the debug.log file when I ran it on a machine which I hadn't used for a month or so:

Maybe you could show us yours?  I tend to agree with Stephen that it's likely a disk space problem.
