■ Current conclusion
目前怀疑是以下提交导致的layer没有释放,从而引起的内存泄露问题
https://dev.thundercomm.com/gerrit/c/general/platform/frameworks/native/+/170546

■ My analysis
有可能是layer创建之后没有导致的,目前正常正在排查

■ Next action
revert提交170546后,在跑脚本验证

■ Current conclusion
revert提交170546后,在用脚本跑了大概3天,该异常依然存在

参考高通case:05803708, 该异常是由于创建太多的layer导致的,以下为高通回复

-----------------
Dear Customer,

Issue is due to the number of layers being created is extremely high (>4096).
SurfaceFlinger can maintain 4096 layers at most. This is expected failure for such cases.

You need to check why these processes are creating these many layers?

Could you check that in your logs?

Thanks,
MC
-----------------

■ My analysis
理由如下:
1. 这个是跑类似压力测试才出现的问题,一般情况不会出现创建layer过多的情况,正常情况下不会对用户的操作有影响
2. 解决该异常需要去修改SurfaceFlinger的内容,风险太大,不可控,可能会引起其他更严重的问题
3. 该问题出现的几率不算高,1/165,而且是压力测试下的概率,正常情况下基本不会发生改异常
因此申请不解

■ Next action

基于以上原因，我认为这个问题可以不解。请从产品的角度也评估一下。

遵循专业意见...若场景不常见，只在指定的压测场景下，且复现率低，可遵循研发意见

根据上面的说明，这个问题不用解，请关闭这个票。谢谢。

经讨论：在特殊压测场景下出现该现象，设计源生，修改恐会造成更大问题——不修改
