Numbered Steps to Reproduce Problem:

1. Startup server on Byondpanel.
2. After typical load time, it immediatelly crashes.

Code Snippet (if applicable) to Reproduce Problem:

N/A

Expected Results:

Server starting up.

Actual Results:

Crash, creation of core file, in couple of times a corrupted .dmb file was created; two times the hosting server reverted its BYOND version back to 511.

Does the problem occur:
Every time? Or how often? Every time.
In other games? N/A
In other user accounts? N/A
On other computers? Works fine when hosted locally on a Windows machine (due to lack of access to ports it's not a hosting alternative)

When does the problem NOT occur? On version 1448

Did the problem NOT occur in any earlier versions? If so, what was the last version that worked? (Visit http://www.byond.com/download/build to download old versions for testing.) As above

Workarounds: None currently, besides using older version - which is experiencing previously reported issues.

Issue was also reported to BP staff due to the odd things happening with BYOND version reverting to 511 upon some of these issues.

511 is not a good choice for reversion; I would recommend going back no further than 512.1448. Too many issues have been fixed since 511.

Yeah, it seems the issue is on the side of BP autoupdater which keeps trying to revert/change version mid-server run. I think this can be closed.

I found what should be causing this issue, and a fix will be available in the next release.

Descriptive Problem Summary:

Pretty shortly into the runtime of the server, another crash occured - not sure if it's the same issue that was already fixed as the error printouts seem slightly different.

Numbered Steps to Reproduce Problem:

1. Start server.
2. Players begin to log back in.
3. Around 10-20 minutes later server crashes, core file generated.

In response to Kokutou
Yeah, it's identical, so I'm merging the threads. Take a look at the crash data: there's absolutely no difference in the most recent few addresses (nearest the top).
