Crash while loading an image

[drewg]

Hi,

I just experienced my first sagetv crash in years, and I think it may be related to the new weather stuff.

I was poking around in the new weather gui last night on an HD300 (connected to a linux server running SageTV V7.1.9.1) when the HD300 "turned off". Sure enough, the sagetv server process had crashed or exited. The last things in the log were:

That is where the log ends, and the new log is from me re-starting the server after its crash. I have a java crash log from that time here:

This is indicating a problem loading an image, not a problem in the weather code -- it could be a fluke or there could really be a problem with the image. Some other line in the log probably indicates what image it was trying to load.

I did a little bit of digging. It looks like something corrupted the file pointer used in Sage's libImageLoader.so

The crash happened here:

# Problematic frame:
# C  [libc.so.6+0x662c5]  fread+0x35

According to the JRE's signal handler, it was a null pointer:

Current thread (0xaec1cc00):  JavaThread "AsyncURLImageLoader" daemon [_thread_in_native, id=29227, stack(0xa6f0d000,0xa6f5e000)]

siginfo:si_signo=SIGSEGV: si_errno=0, si_code=1 (SEGV_MAPERR), si_addr=0x00000000

According to gdb, libc was accessing the file pointer passed to fread():

45        _IO_release_lock (fp);
46        return bytes_requested == bytes_read ? count : bytes_read / size;
47      }

Are you sure there is nothing in the code that could access an invalid file (say, by not opening it..).

BTW, this is a Xeon with ECC memory, so I do not think it is a random memory error.

EDIT: I also just changed all the fan-art stuff around, from using Fuzzy's fanart for malore menus to using some other thing which puts fan art onto malore menues. Maybe that somehow screwed up something, and the weather just got unlucky..
