 使用的是2.8.4版本的SDK 现象是：业务进程出现过OOM，后续BlockedThreadChecker在执行过程中也因OOM抛出异常 日志如下： ``` OOM caused by java heap space occurred, allocate size: 48 bytes, type: Ljava/util/WeakHashMap$EntryIterator; garbage-first heap total 524288K, used 329140K [0x00000000e0000000, 0x0000000100000000) region size 1024K, 0 young (0K), 0 survivors (0K) Metaspace used 118670K, capacity 127785K, committed 128356K, reserved 258048K class space used 15242K, capacity 16640K, committed 16792K, reserved 145408K current stack trace: at java.util.WeakHashMap$EntrySet.iterator(WeakHashMap.java:971) at io.vertx.core.impl.btc.BlockedThreadChecker$1.run(BlockedThreadChecker.java:51) - locked <0x00000000e2a38fb0> (a io.vertx.core.impl.btc.BlockedThreadChecker) at java.util.TimerThread.mainLoop(Timer.java:555) at java.util.TimerThread.run(Timer.java:505) Exception in thread "vertx-blocked-thread-checker" java.lang.OutOfMemoryError: Java heap space at java.util.WeakHashMap$EntrySet.iterator(WeakHashMap.java:971) at io.vertx.core.impl.btc.BlockedThreadChecker$1.run(BlockedThreadChecker.java:51) at java.util.TimerThread.mainLoop(Timer.java:555) at java.util.TimerThread.run(Timer.java:505) ``` 初步怀疑是OOM导致的BlockedThreadChecker抛出异常，没有复现条件 是否可以考虑将BlockedThreadChecker的时间周期拉长，或者关闭该检测机制 -- This is an automated message from the Apache Git Service.
