[0.14.7] [Oxyd] MP server crash - addr2line not found?

[Denubis]

These seem to be mildly common.

16.04 machine. headless. 8x2.5GHz, 8GB ram.

Code: Select all

Is there anything that seems to cause it or is it completely random?

We're doing massive-server testing for Steejo's streams, so it *feels* like someone with a wonky IP connecting. But ... writing that out, I don't really think that's the case. I suspect it's covering a rare crash with an unlinked library in 16.04. This error is calling sh with "addr2line". None of my scripts https://github.com/Denubis/headlessFactorio use sh or "addr2line" -- but other crashes on the server dump memory just fine. (Fresh install of 16.04, no specific installing of support packages). Perhaps audit your crash reporting scripts for one that uses addr2line in an odd way? I'm not sure what the underlying crash is because this is obscuring that report.

Factorio uses add2line to convert memory addresses to function names. If you don't have it installed, it won't convert.

That's not the problem, though. All it means is that the stacktrace doesn't have symbols in it, so we have to do some extra work to symbolize it. The stacktrace is as follows:

Code: Select all

/tmp/factorio-CQCaqH/src/Util/CrashHandler.cpp:105
/tmp/factorio-CQCaqH/src/Util/CrashHandler.cpp:215

Still, that doesn't tell me much.

Should be hopefully fixed in 0.14.11.
