I hope I am providing enough information to get some help. We have been playing on 0.4.5 without issues for a while. I just upgraded the server (on Linux Mint 13) and clients (all on Windows XP) yesterday to 0.4.6. The process I used for the server was to build 0.4.6 with 'cmake . -DRUN_IN_PLACE=1' and copy the files into the ~/minetest folder over top of the 0.4.5 files except for the 'worlds' folder.
Everything appeared to be working fine till tonight. We had me, my 2 kids, and 2 of their friends playing all at the same time. We decided to dump a bucket of lava onto one of their houses to watch it burn, and it was cool... for about 10 seconds. Then we all received a "Server shutting down" message. At first, I blamed my brother, so I called to yell at him and he said he hadn't done anything, so I ssh'd in and checked the uptime. Sure enough, uptime hadn't reset. So, I checked to see if the server was running and it wasn't. So, I restarted it. My son logged back in and we thought we were fine. Before a second person could connect, the server crashed again. Here is what it is saying:
(home dir changed to protect the guilty.)

Now, after restarting, I can log in for about 10 seconds before it crashes again. I'm hoping there might be a quick fix to remove this block so we can continue building on this world.
Along with this note, we had a lava block placed at the top of a tower prior to upgrading and it never seemed to be a problem. It wasn't till we added this lava block after the upgrade that it began to crash.
Thanks for any help.
