DreamDaemon crash out

ID:1615194
 
Jul 1 2014, 11:11 am
BYOND Version:506
Operating System:Linux
Web Browser:Firefox 30.0
Applies to:Dream Daemon
Status: Open
Issue hasn't been assigned a status value.
Descriptive Problem Summary:
DreamDaemon crashes out completely giving a long detailed crash report.

I'd like to be detailed about this crash report, but so far it happens at very random intervals and I'm unable to reproduce it. It happens rarely when save file operations are done.

Below is a very cryptic log file. Every time it happens, it corrupts the log file to be practically unreadable. If required I can submit a download link to the 'core' file.

It looks like a savefile is corrupt when DD tries to access it. does Import15() use savefiles?

It does.

Do you happen to have a copy of a savefile you know causes the crash? The savefile code is an area where we've always had some random issues that have been difficult to solve, but if there's a specific file causing instability then it might be possible to trace the issue in a test environment.

In response to Lummox JR
Unfortunately not. That specific function is accessible to my players to use, so I don't have access to it. Would there be any information detailing it in 'core'?
Jul 2 2014, 6:57 am
I'm not sure, but I doubt it'd be easy to tell the filename from the core's info. I strongly suggest putting in some debugging so you have something printing out to a log, preferably via text2file() which I think will flush, spitting out the filenames being accessed so that you can get a handle on which files seem to be causing the problem.
