OutOfMemoryError 堆栈溢出

[linlaoye]

我使用python写了7条线程，一条负责疯狂随机点击滑动坐标（模拟monkey操作），剩下6条负责查询某个元素是否存在，存在则点击元素（用来点击一些顽固的关闭按钮），6条线程有上线程锁，有序竞争。跑了1天左右就会出现OutOfMemoryError

• 手机型号：Android13 三星A54
• uiautomator2的版本号：3.2.3
• 手机截图：无
• 相关日志：

@mingyuan-xia
麻烦大佬有空帮忙看一下这个问题， 我也出现了， 尤其是在执行压测脚本中容易出现，我跟上面楼主都出现了相同的OutOfMemory

唯一不同的错误就是androidx.test.uiautomator.ByMatcher， 貌似是与递归调用或内存泄漏有关（ByMatcher.findMatches 被多次调用
