It’s definitely WAMP, most likely the ‘W’ part. (I tried this on Windows 7) XAMPP has even more trouble. Apache is being disrupted and crashed at times, probably because of Windows User Account Control (UAC) security settings and/or IIS. You should get a warning about this when you install XAMPP on Windows. I haven’t test to see if that’s the cause, but it seems likely.

What does work is LAMP, so just do the migration on your webserver or localhost. I’ve had no problem doing it all on Nexcess.net’s WordPress hosting with over 61,000 posts and 1100 users converted with the default settings of 100 rows at a time with a 1s delay.
Did anyone ever get to the bottom of this? I have the same problem. I think it may have to do with WAMP.
