Got crash when calling rocketmq::LogUtil::LogMessageFull

1. Please describe the issue you observed:
   Since Jul 13 2021, our rmq-client-cpp was really stable in the production environment, it's version is "2.2.0"; but got crashed today, below is the trace:

2. Please tell us about your environment:

• What is your OS?
  NAME="CentOS Linux"
  VERSION="7 (Core)"
  ID="centos"
  ID_LIKE="rhel fedora"
  VERSION_ID="7"
  PRETTY_NAME="CentOS Linux 7 (Core)"
  ANSI_COLOR="0;31"

• What is your client version?

V 2.2.0

• What is your RocketMQ version?

V4_8_0

3. Other information (e.g. detailed explanation, logs, related issues, suggestions on how to fix, etc):

和以往不同的是这个时刻rmq 打出了大量的日志

Can we solve the problem by upgrading the the rocketmq-client-cpp version to V5.0.0 ?
By the way, our program use 15G memory, and the machine have 62G memory total.

请问这个问题解决了么？我也遇到了同样的问题。看着像是并发调用producer.start 导致的。但是我还不太确定。求大神。

• 场景
  python scheduler定时任务中，多线程生产消息事件

• 环境：

多线程并发start\shutdown会有问题。修改项目启动的时候初始化解决了。
