INspect that WAL segment or possibly the one immediatly following it
in comparison to another copy if you still have it on the master or a
central WAL repository.

A standby crashing meanwhile copying in a WAL segment and/or synching
one to disk could result in ramdon corruption.

If you have another copy of the segment and does not compare equal to
the one your standby is trying to read, try another copy.

The admin list is the right one for such a post probably.
