    My springboard crashed today and I'm trying to figure out what was the reason. I was on Facebook and phone crashed. How do I read it? My ram was around 85% used at the time.

    Man I wish I knew how to decipher those. I think you need to have an understanding of debugging to figure it out. I've spent many hours googling this topic and never really got anywhere.

    When you tap on Facebook, does crash reporter list any "suspects"? Usually if it can give you that information, sometimes that points you in the right direction. But I've had times when it said one thing was the main suspect but it ended up being something completely different. I stopped using crash reporter unless a dev asks me for a log. Now I do it the manual way...disable tweaks one at a time to find the problem. Sometimes though, apps from the App Store have crashing issues. Not sure if Facebook is one of them though. I don't use Facebook.

    I'm gonna keep my eye on this thread though in case someone posts some type of beginners guide to deciphering crash logs. If love to learn more about this.

    Edit: if you search/look through the first 3-5 pages of threads, you'll see numerous threads that discuss the Facebook app crashing. You can probably find some helpful information in those threads. Good luck. Wish I knew more.

    Thanks for the long response most people on here just tell others to search and don't help anybody out.
    I need to figure out what's causing it. I do have copic(pictures for contacts and messages). That one is crashing the SMS app. Hopefully they update that I don't know if that would have anything with the springboard crashing.
    I also have dock( side app switcher) with activator.
    For the Facebook one it doesn't have any culprits for suspected crashes. So I'm not sure.
    Does the springboard crash if the ram is very high? Never had this problem stock.

    Not sure about all your problems. I don't have any crashes or anything like that on my device but at the same time I don't have a ton of stuff installed. And pretty much all my installed packages are from the most well known and well respected devs on Cydia.

    But I can tell you that low ram usually doesn't (can't?) crash the springboard. If anything it will cause an app to crash. My guess is that one of your packages is causing springboard to crash. Try going through them one by one disabling them until the problem goes away. Once it stops, odds are that tweak is the problem.

    If/when you find out what's causing the crashes please post that information here so others will be aware of it too. Good luck!

    What tweaks do you have installed? We might be able to point out tweaks with known bugs...

    I'll be another one to add that the FB app is buggy as hell. I watched it crash on my husband's completely stock, never been JB'd iPad several times this afternoon.

    Atomic Browser is also crashing to Springboard almost every time I download a file. Since that's my usual go-to app for downloading widgets, icons, and the like, it's been pretty irritating the last two weeks.

    But in that instance, I have an easily replicated situation: Too many apps in the switcher, too many open processes. Kill all background apps, and it will *usually* behave. Nothing fixes Facebook, and most likely nothing will until they update the app.

    I'd love to see someone chime in on how to read these reports. Unless they list a suspect, I have no clue what they mean, and I'd like to be able to triage more of this stuff myself.

    Coming from an OSX standpoint, it's always helpful if you post the entire crash log. You'll want a fresh one, i.e., one from when it just crashed. Crash logs tend to be long so if you post it, it'll probably be a long post.

    I don't read crash log, but I know people (engineers) who do and the little I've picked up from them can help decipher things somewhat.

    Apps process things in threads. The crash log will tell you which thread crashed and may offer some reason as to why. High memory use in and of itself won't crash an app, but if an app is asking for memory that isn't there because of a low memory state that could force the app to crash.

    Typically, crashes are because apps ask for something that either they aren't allowed to have or that isn't available (such as more memory when it's not there). But we won't know unless we see the actual crash log.

    Interesting stuff!

    Here's a follow on question: why do some crashes to Springboard not generate logs? Going back to Facebook as an example, I have exactly one crash report, yet I know it's sent me back to the Springboard at least 4-5x a week. (This is why I stopped even looking at them on my iPad; no real point since there wasn't any data to work with at all.)

    Well, if it was FB crashing you'd look for the FB crash log, not the Springboard. Even if FB took out the Springboard the original crash was from FB so that's the log you'd look at.

    Sometimes it does happen so fast though that a log doesn't get written, or only partially written.

    Here's a log from my most recent crash of FB. This was due to Copic, which had two updates that day (Friday the 8th). I know that because Copic was crashing when I was scrolling in AddressBook. Then I opened FB and it crashed right away. If you look at the first few lines of the log it's pretty evident that it crashed trying to access my contacts when the FB app was opening. Again, I don't read crash log, but some stuff jumps out at you when you put things in context.

    ive sent an email to the copic developers explaining the problems its having. Let me know if you have this problem too.
    When you first open messages app clean it will crash. sometimes it will crash 2-3 times before its fine. It shows one person for the whole list for a second then crashes.
    Also in contacts app it will flash/black for a split second and then be ok.(having trouble reproducing now).
    hopefully they come out with a fix soon

    Have you checked Cydia for updates? There were two on Friday the 8th. I suppose to address the issue. I have Copic so I experienced the exact same thing you did.
