It seems that the function md5_file() fails to operate on large files. I believe this issue occurs when the file is larger that 2gb. Slightly smaller files (around 1.8gig) seems to work fine.

When trying to access these large files, php generates the following error:

Warning: md5_file(): Unable to open file in XXXXX on line XXX

Reproduce code:

Expected result:
return a valid md5hash

Actual result:
Warning: md5_file(): Unable to open file in XXXXX on line XXX

returns an empty string

This code was running as part of a shell script and not via apache (module or cgi)

Also the shell command md5sum works on the file the files that the code above fails on.

Was php compiled with large file support?
