[Sony Cross-Device General] mionica:
Evrika!

So here's how zygote's process tree looks with no Xposed installed:

PID FILES TASKS CONTEXT [CMDLINE] EXECUTABLE
663 18 6 u:r:zygote:s0 [zygote] /system/bin/app_process32_original
[b] 1422 [color=blue]250[/color] 111 u:r:system_server:s0 [system_server] /system/bin/app_process32_original[/b]

2367 25 16 u:r:untrusted_app:s0 [org.pocketworkstation.pckeyboard] /system/bin/app_process32_original
...

Then, here's how the same process tree looks on the first boot after clearing /cache (using xposed-sdk21-arm-20150426.zip):

PID FILES TASKS CONTEXT [CMDLINE] EXECUTABLE
665 36 6 u:r:zygote:s0 [zygote] /system/bin/app_process32_xposed
997 7 1 u:r:untrusted_app:s0 [logcat-vtime-sXposedStartupMarker:DXposed:Iappproc:IXposedInstaller:Iart:Flibc:FDEBUG:I] /system/bin/logcat

[b] 2217 [color=orange]358[/color] 112 u:r:system_server:s0 [system_server] /system/bin/app_process32_xposed[/b]
17716 91 32 u:r:platform_app:s0 [com.android.systemui] /system/bin/app_process32_xposed
17738 49 13 u:r:platform_app:s0 [com.sonyericsson.capabilities] /system/bin/app_process32_xposed
17764 59 17 u:r:untrusted_app:s0 [android.process.media] /system/bin/app_process32_xposed
17878 93 30 u:r:untrusted_app:s0 [com.google.android.wearable.app] /system/bin/app_process32_xposed
...

And finally, here's the same process tree, on the second boot:

PID FILES TASKS CONTEXT [CMDLINE] EXECUTABLE
659 55 6 u:r:zygote:s0 [zygote] /system/bin/app_process32_xposed
1002 7 1 u:r:untrusted_app:s0 [logcat-vtime-sXposedStartupMarker:DXposed:Iappproc:IXposedInstaller:Iart:Flibc:FDEBUG:I] /system/bin/logcat
1003 9 3 u:r:system_server:s0 [xposed_service_system] /system/bin/app_process32_xposed
1004 9 4 u:r:untrusted_app:s0 [xposed_service_app] /system/bin/app_process32_xposed
1008 8 1 u:r:untrusted_app:s0 [xposed_logcat] /system/bin/app_process32_xposed
[b] 1680 [color=red]951[/color] 111 u:r:system_server:s0 [system_server] /system/bin/app_process32_xposed[/b]
2244 125 35 u:r:platform_app:s0 [com.android.systemui] /system/bin/app_process32_xposed
2268 68 13 u:r:platform_app:s0 [com.sonyericsson.capabilities] /system/bin/app_process32_xposed
2296 88 21 u:r:untrusted_app:s0 [android.process.media] /system/bin/app_process32_xposed
2436 129 30 u:r:untrusted_app:s0 [com.google.android.wearable.app] /system/bin/app_process32_xposed
...

Hence the question: what the hell is happening? So let's look at what files are opened by system_server in this later case:

busybox ls -l /proc/1680/fd/|busybox awk '{print $9 " " $11}'|busybox sort -n

That is, the exact same file is opened by a single process for 688 ****ing times.

At this stage, I'm pretty darn sure we know exactly

what gets leaked (file handles to /data/dalvik-cache/arm/system@framework@boot.oat),

when that happens (all the time, though the rate is extremely low during the first boot, when the system recompiles everything) and

why we're seeing crashes (those leaks accumulate to the point where the kernel runs out of file handles; the more apps you have, the sooner that happens).

I rest my case, and have reported this here.

Failure analysis

The fact that only handles to one specific file are leaked seems to suggest that the point of failure is unique

Comparing the number of file handles between a non-Xposed boot and the first Xposed boot, it's appears likely that the point of failure is on a path that's also exercised during the first boot, but which results in a lot of fopen() errors; more specifically, I expect that that .oat file is kept open with a write lock by the process that recompiles the applications for ART, thus prevending the Xposed system server from opening it, thus giving it nothing to leak

Furthermore, the fact that the first boot appears stable, is probably just an appearence; meaning, given enough time, a first-booted system will still be killed by the leak;

The reason why the first boot is so much more stable is probably a consequence of the rate at which handles are leaked after boot completes, i.e. if the rate is much slower than during boot, it can be reasonably expected that the first boot will appear stable for a long time

The above is also supprted by the fact that, if the leaking rate were constant, everybody would see reboots within 25mins of resetting the device

This is further supported (intuitively) by the fact that, at boot (on boot #2 and subsequents), 687 handles have already been leaked, which happens to be almost 20% of the total number of files the kernel could keep open on our Sony's;

The rate at which handles are leaked seems to strongly correlate with the number of processes/apps on a system; the experienced lifetime of systems with few applications (such as mine or the OP's) is high, appearing to be stable (though I've seen my first random reboot yesterday :D), whereas people who use cartloads of applications could see reboots within hours or less;

The above seems to indicate that the affected Xposed code path has to do with resuming or loading apps.

Oh btw - if you like those process lists, I've attached the thing that makes them possible ;)
