00:29 OldCoder thexyz, The SIGKILL issue may not be related to the MT code. Rebooting seems to have made it disappear for now. Proceeding with some conversions.
00:33 OldCoder thexyz, I spoke too soon. Sorry. SIGKILL occurred later on. Looks like there's a dangling pointer somewhere. I've tried gdb but the problem occurs outside the active process.
00:33 OldCoder thexyz, So I've managed to convert a few worlds but can't convert any others yet.
00:44 hmmmm    'a dangling pointer'
00:44 * hmmmm  sighs

01:39 OldCoder thexyz, Explanation: The SIGKILL issue is related to memory use. Conversion requires GB of RAM for some worlds. I've increased swap space but this does not seem to be sufficient. At least there is an answer.

03:16 hmmmm    hrmm
03:17 hmmmm    was there a reason why you changed ServerMap::findGroundLevel from scanning through the nodes to until ground is hit into finding it from noise?
03:19 hmmmm    i guess there's nothing more wrong with that than scanning downward
05:00 OldCoder thexyz, More information if you're curious. One world requires 10GB of memory to convert. That is more than the typical PC :-)

09:06 OldCoder thexyz, Final results for Sunday night. Largest sqlite3 file converted using latest code. World seems to work. Remaining worlds will be done. One issue is slow shutdown on SIGINT. Another is Windows support. These are outweighed by >4GB support, speed, and apparent reliability. I'd continue to update the LevelDB code when Google does.
17:53 OldCoder thexyz, conversion appears to be a success. Nothing to add to the conclusions posted last night.
17:53 OldCoder Calinou, your world is now in an entirely new database format. Can now grow to a large size. Should also be a bit faster. Report problems.
