Hello.

I had a validation error on my laptop today and am not sure what caused it. I don't know if it was just coincidence but if not, I'd like to know what to do against it.
This is the particular result I'm talking about

Probably just a fluke. The only thing of note I see is

2007-01-29 08:59:55.0904 [CRITICAL]: Fstats file '../../projects/einstein.phys.uwm.edu/h1_0376.0_S5R1__1110_S5RIa_0_0' has incorrect checksum.
2007-01-29 08:59:55.0904 [CRITICAL]: Checkpointed checksum: 0, computed: 120635127

But if you start to see a bunch of them then post back and somebody will take a closer look at them and maybe will have a solution (I certainly don't).

Since a checksum is a

Since a checksum is a (sinplistic) form of hashing, the odds of getting a value of zero are 1 in the number of possible results or generally 1 in 4 billion. This means that the 0 y ou got probably is the result of a file getting zero byted somewhere.

It seemed to have been a once

It seemed to have been a once in a lifetime checksum error. I have two other results in so far and they seemed fine for the validator. Thanks for your help though, guys.
