      Is this a random occurance or can you reproduce the problem with a
      specific log file?

      Also, can you re-compile with the --enable-debug option so a better
      backtrace can be obtained?

        I reran webalizer with the same log file and it appeared to have
        worked correctly. This has happened twice for the same account a few
        weeks apart.

        Yes, that I am not sure of. I have asked my collegues who know more
        about cpanel. If we cannot, then I hope that one of these times I can
        get it into a re-creatable state. Then I create build webalizer with
        debug symbols....

        Just wondering if this jogged any memories.
