Someone keeps logging in and has crashed the server 3 times now I believe mrwiskki is working on this but I am not sure so I decided to post this Thanks for the help!
Yeah, its a conflict between veinminer and the RF hammers. The blasted things crash the client anyways (tried to test with them, and ended getting booted to desktop) so I'm thinking its probably best to just ban the things, until the next version of redstone arsenal/exastris/veinminer come out and fix this issue.
