[I] bthread定时器等待了12秒都没得到执行，程序生成core的过程中又恢复了，想问下要如何定位这种问题？ (brpc)
weingithub opened a new issue, #2455:
URL: https://github.com/apache/brpc/issues/2455
**Describe the bug (描述bug)**
bthread定时器等待了12秒都没得到执行，触发了程序检查bthread卡住的assert，而在程序生成core的过程中又恢复了。
**To Reproduce (复现方法)**
在正常业务中，创建pthread线程和bthread定时器，在pthread线程中定时检查定时器的更新时间。超过一段时间未更新，则assert
**Expected behavior (期望行为)**
程序不会触发bthread卡住的assert
**Versions (各种版本)**
OS: centosx
Compiler: gcc
brpc:
protobuf:
**Additional context/screenshots (更多上下文/截图)**
想问下，一个是如何定位这种bthread卡住一段时间的这种问题？如何查看当时的运行截面？之前遇到过使用pstack去dump查看，结果
bthread似乎又被恢复了。我这个也类似这种现象，bthread不知道因为什么原因卡住了，然后又恢复了。

存在这么个情况。之前也解过一些混用导致的加锁卡死的问题。不过那个问题，通过pstack是能够看出来的
