KOOM ForkDump时子线程挂起在JniMethodEnd

ForkDump时子线程挂起在JniMethodEnd

Open cclover opened this issue 2 years ago • 3 comments

用的最新v2.2.1， 2.1.0也碰到这个问题，只修改了gradle和AGP版本，其他没变，应该不影响。表现就是一下正常一下卡住，有时候没问题，杀进程后跑2次就有问题，然后可能就一直不行，过一会又可以，没啥规律。在2个Android10设备上出现。一个小米8（开发版ROM），一个荣耀V30PRO （自用正式版），其他一些设备没出现，不知道是不是用的少，还是什么。

dump卡住时， kill -11看了下堆栈。比较怪异。卡在子进程JNI返回，应该是kNative变kRunnable时。但是不应该， JNI进入时应该只修改了status， flag没有kRequestSuspend，不应该等，除非这个线程被执行了Suspend。

HWOXF:/data/data/com.kwai.koom.demo $ ps -A  | grep com.kwai.koom.demo
u0_a453      19802   671 5967380 149652 do_wait             0 S com.kwai.koom.demo
u0_a453      20697 19802 5889728  53464 futex_wait_queue_me 0 S com.kwai.koom.demo

但是主进程是正常返回，在等子进程。 Fork后子进程也没其他动作，比较怪异，不知道你们是否有遇到过。

有主进程的trace么？看下其他线程在做什么

把alarm超时设置600秒。然后抓了bugreport. 子进程没dump出来，用kill -11看就是卡住JNI END

---- pid 24021 at [unknown] ----
Dump failed, likely due to a timeout.

本地复现不了这个问题，推测可能是fork的时候有别的线程拿到了锁，你那边开发版的ROM有源码和符号表么，这两行帮忙把inline调用解析出来确认下是哪个锁，应该不是resume_cond_，否则就是必现问题了。

另外帮忙把你复现的apk发一下，我再复现试试。
