zyearn edited a comment on issue #1066: metrics fork出的子进程夯住 URL: https://github.com/apache/incubator-brpc/issues/1066#issuecomment-600977136 原因：在fork中会调之前由pthread_atfork注册的fork_handler，如果在fork_handler还调了pthread_atfork，由于glibc2.28之后的fork会和pthread_atfork抢一把锁，于是发生死锁。 FIX：https://github.com/apache/incubator-brpc/commit/2f8fc37d52c2a02ee6f348aaa52c7ded4a4844c3
