Freezes in midgame

[Edgar]

After a while playing a game (~ 1 hour) the emuator freezes, all I can do is to kill the process.
This does not happen with a specific game, or a specific part of a game; it looks more like random.

WORKAROUND: Use the Windows version of zsnes 1.51 via WINE.

Status changed to 'Confirmed' because the bug affects multiple users.

[Jonas Oscarsson (joscarsson)]

I am seeing this as well. After upgrading from Ubuntu 12.10 to 13.04 a bug was introduced which caused the emulator to crash as soon as a game was selected to be played. When that bug was fixed, this bug was introduced instead. It is now playable, but without exception it hangs in the middle of the game after ~1 hour. Only thing that helps is to kill the process and restart.

Let me know what information I can give to help you troubleshoot this. coredump?

I am also seeing this on 13.10. I saw it on 13.04 before the upgrade as well. Did not have this issue when using 12.04 at a previous time on the same hardware with the same ROMs.

[Alexander Klauer (graf-zahl)]

Me too. Unfortunately, there does not appear to be a debug package for zsnes. This is what I found during a freeze:

I ran into a very similar behavior as well. There is an ongoing discussion at ubuntuforums where I posted some info but I think it is better suited here. Here is the thread:

http://ubuntuforums.org/showthread.php?t=2159402

So this is on Ubuntu 13.10 with znes package version 1.510+bz2-5ubuntu3. Very similar behavior -- the application stops responding to input after 30 minutes or so and can only be SIGKILL'd. I ran strace on the hung process and it appeared to be stuck in a futex-based deadlock:

futex(0x9851848, FUTEX_WAKE_PRIVATE, 1) = 0
futex(0x9851848, FUTEX_WAKE_PRIVATE, 1) = 0
futex(0x9851848, FUTEX_WAIT_PRIVATE, 2, NULL) = -1 EAGAIN (Resource temporarily unavailable)
futex(0x9851848, FUTEX_WAKE_PRIVATE, 1) = 0
futex(0x9851848, FUTEX_WAKE_PRIVATE, 1) = 0
futex(0x9851848, FUTEX_WAIT_PRIVATE, 2, NULL) = -1 EAGAIN (Resource temporarily unavailable)
...

This is presumably the same bug as https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=740860 which was fixed in version -7.

[Brandon "Stickman" Arnold (manwithbundleofsticks)]

Still happening to me on 14.04, happens every 40 minutes or so. Also deletes any save progress that occurs while in-game, I've had to rely on save states instead.

[Jan (thesheeep2)]

I can confirm that this is still an issue.
I'm using the latest version of Linux Mint, 17, (running the Ubuntu based version, of course).

[Ben M. (bmhm)]

Fixed in debian since 10 May 2014, still not fixed in 14.04 LTS since Aug. 2013. What can we do to help get this fixed into ubuntus repositories?

[Regine (cap-is-)]

Hey all,

I can confirm this as well:
zsnes Version: 1.510+bz2-6
Ubuntu 14.04.2 LTS

[Brian Morton (rokclimb15)]

Bug is fixed in Wily due to a resync with upstream.

http://changelogs.ubuntu.com/changelogs/pool/universe/z/zsnes/zsnes_1.510+bz2-8/changelog

Also, they added a debug package, which is great news.

Thank you for taking the time to report this bug and helping to make Ubuntu better. However, I am closing it because the bug has been fixed in the latest development version of Ubuntu - Xenial Xerus

This is a significant bug in Ubuntu. If you need a fix for the bug in previous versions of Ubuntu, please perform as much as possible of the SRU Procedure [1] to bring the need to a developer's attention.
