- l checked the native method `java.net.PlainSocketImpl.socketAccept(Native
Method)` in
[openjdk](http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/file/9d617cfd6717/src/solaris/native/java/net/PlainSocketImpl.c),
**line709-721**, in which it changed from 0 to -1. and then timeout of -1 is
interpreted as an infinite timeout. In some cases, [-1 was interpreted as a
larger positive integer](https://lwn.net/Articles/483078/). so this issue
always happend after 49days. It's my wild conjecture.
