[Kea-users] lease reading error

text files like kea_leases.csv reach really good compression ratio. It
shouldn't reach more than 5Mb, but it is still to much for mailing list
so if you could upload it somewhere.

Or change logging severity to DEBUG with debug level 99 and see if there
are additional logs.
