...
A good way to debug this is the next time it happens, SSH into the remote repo, cd into the objects folder and do an ls -al.

Is SHA-1 secure for password storage?
...sharing of a dictionary or brute force attack. It is a derivative from the time-memory trade-off first described by Hellman in 1980. Assuming that you have N possible passwords (that's the size of your dictionary, or 2n if you consider brute-forcing a hash function with an output of n bits), there i...
