Re: [SVN-DEV] Loading dump with 1.4.x works, 1.5.x/1.6.x generates checksum error

I'm not the one actually running the p42svn.pl script... it's being done
by an admin at a remote site and then he's transferring the resulting dump
file to me to load into the SVN server.

But... it looks like he was using p42svn.pl version 0.20... so perhaps
that is the problem. He retried the conversion using 0.21 and noticed the
resulting dump file is almost 3 times as large. With 0.20 the dump file
was about 4.5G and with 0.21 it's 13G.

Do you know of any reason why the new dump file would be so much larger?
