Question

当我使用jstack检查进程时，我得到了这个日志：

-dontwarn retrofit2.**
-keep class retrofit2.** { *; }
-keepattributes Signature
-keepattributes Exceptions

-keepclasseswithmembers class * {
    @retrofit2.http.* <methods>;
}

并且有很多其他人喜欢这样。首先我认为这是因为冰连接超时设置问题，因为我发现第147行中的Outgoing.java是这样的：

 "poolTaskThread-4" prio=10 tid=0x00007f09300ff800 nid=0x69ce in Object.wait() [0x00007f0aa5271000]

所以我添加了Ice.Override.Connection = 200000，但问题出现得越早，我该怎么办冰线~~

Answer 1

Ice有一个名为Ice.CacheMessageBuffer的参数，你可以设置这个

Ice.CacheMessageBuffers=0

这不会调用directbuffer，你可以尝试一下，它会改进JVM GC。

如何检查Ice thread等待对象
