Kernel Panic. Help finding out the reason.

Question

Hi guys. Last couple months I have been experiencing constant restarts on my macbook air. Some times it works perfectly, but there are days when it reboots 10-15 per hour! I tried everything, exept of taking it to applecare. Look at the report I copied and tell me if you can find something out of it. Thank you very much peeps.Anonymous UUID:       3C09E1E9-692B-2878-7B07-C19572199A1ASun Jun  1 04:17:44 2014panic(cpu 1 caller 0xffffff8004654cd4): "a freed zone element has been modified: expected

Linc Davis · Answer

That panic was not caused by third-party software. If the problem is recurrent, the possibilities are:A stale or corrupt kernel cacheA damaged OS X installationA fault in a peripheral device, if anyCorrupt non-volatile memory (NVRAM)An internal hardware fault (including incompatible memory)An obscure bug in OS XYou may already have ruled out some of these.Rule out #1 by starting up in safe mode and then restarting as usual. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.You can rule out #2 and #3 by reinstalling the OS and testing with non-essential peripherals disconnected and aftermarket expansion cards removed, if applicable. Sometimes a clean reinstallation may solve a problem that isn&#x27;t solved by reinstalling in place.Corrupt NVRAM, which rarely causes panics, can be ruled out by resetting it.If your model has user-replaceable memory, and you&#x27;ve upgraded the memory modules, reinstall the original memory and see whether there&#x27;s any improvement. Be careful not to touch the gold contacts. Clean them with a mild solvent such as rubbing alcohol. Aftermarket memory must exactly match the technical specifications of the machine.Apple Diagnostics or the Apple Hardware Test, though generally unreliable, will sometimes detect a fault. A negative test can&#x27;t be depended on. Run the extended version of the test, if applicable.In the category of obscure bugs, reports suggest that FileVault may trigger kernel traps under some unknown conditions. Most, though not all, of these reports seem to involve starting up from an aftermarket SSD. If those conditions apply to you, try deactivating FileVault.Even if FileVault is not active, an aftermarket SSD may be the cause of kernel panics. Check the manufacturer&#x27;s website for a firmware update.Connecting more than one display is another reported trigger for OS X bugs.If the system is not fully up to date, running Software Update might get you a bug fix.In rare cases, a malformed network packet from a defective router or other network device can cause panics. Such packets could also be sent deliberately by a skillful attacker. This possibility is something to consider if you run a public server that might be the target of such an attack.Otherwise, make a "Genius" appointment at an Apple Store, or go to another authorized service provider to have the machine tested. You may have to leave it there for several days. There isn&#x27;t much point in doing this unless you can reproduce the panic, or if you can&#x27;t, it happens often enough that it&#x27;s likely to be repeated at the store. Otherwise you may be told that nothing is wrong.Print the first page of the panic report and bring it with you.

From posts I&#x27;ve read here and elsewhere, these "freed zone element" panics are often cause by malfunctioning memory cards. Also, the second log you posted lists "possible memory corruption." If this was my machine, I would start with trying to replace the memory or having the Apple geniuses do it.

I tried running in Safe Mode for almost a day. Interestingly, no kernel panics occured during that time. You all know that the defective RAM is worst for Macbook Air, because its integrated to logic board. That is why I would like to eliminate all other causes before I deal with RAM issue. Thank you for your rapid replies on my topic. I really appreciate it.
