The checks are going at a really slow pace, but here are some preliminary numbers.

I have gone through 45696 crashes.  I did find some repeat signatures, here is the distribution so far.  The first number is the number of times that md5sum was found, the second number is the md5sum itself and the last is the crash uuid.

Is this the kind of stuff you are looking for?

ughh.. that didn't paste well at all, here is the same data without the md5sums.

It is the type of data we are interested in, thanks.  The same dump twice is not that interesting but 25 times - I'm very curious.

Here is the list of repeated crashes, nothing stands out..  I found the source of that repeating signature (f0a156d74a00d4bdf51f9990eeeace7c).  Its the crash report I submit for testing the collectors.
