Answer 1

What version of PHP are you using?

This is a well-known bug on PHP, though it was fixed in 5.3.2RC3.

See these bug reports for more info:

• Fixed: Bug #51167 crypt() hangs randomly when called with a salt
• Assigned: Bug #51424 crypt() function hangs after 3rd call

You can use hash_hmac() instead of crypt() for a quick fix.
