After a bit more examination, his actual user file need only be 48k.
I found ~128mb of slashes \\\\\\\\\ in one of the user names added to the file.
I believe it's related to the same bug we fixed in SVN 17,
bug 208 regarding bans.
Samusaaron3, This is a known issue for our release ULX 3.31 version for banning people with slashes in the name. Though we'd not seen this reported for any other instance, the same would hold true for adding users with slashes in the name. We've fixed this in SVN code, and hope to have a real release soon.
I've attached the 'fixed' users.txt file for you.
You may still find a few quirks, as I notice a few myself, but hopefully none as bad as you had.
In the future, until we make a new release, be careful of adding people with slashes in the name through console. Adding through manual txt file edit should still work.
Or, feel free to help us test SVN.
