如何解决usr/ce1800v/bin/ce1800vd.sh：第315行：wait_for：没有进程30388的记录

我有一个名为 ce1800v 的服务。它的主要进程是ce1800vd.sh。

每秒，它使用命令 cat /proc/${process_id}/stat

检查其子进程的状态

如果此命令的返回值不为零或进程状态为Z（表示僵尸状态），我将重新启动服务。

以下是部分代码：

process_info=$(cat /proc/${process_id}/stat 2>/dev/null)
if [ $? -ne 0 ]; then
    error_info="Get process ${process_id} info Failed."
 else

然而，莫名其妙地，检查命令失败并输出（/var/log/messages）

usr/ce1800v/bin/ce1800vd.sh: line 315: wait_for: No record of process 30388

我搜索了很多，发现 bash 4.3.42 有一个具有相同现象的错误。然而不同的触发原因。

我没有设置 lastpipe 选项。

这个问题几乎每天都在发生，但没有规律。

我尝试从 4.2.46(2)-release (x86_64-redhat-linux-gnu) 升级我的 Centos bash。到4.4.0(1)-release (x86_64-unkNown-linux-gnu)。但无法重现该问题。所以我想也许还有其他原因。

我现在很困惑，不知道接下来如何进行这个分析。

我想知道为什么？

谢谢！

解决方法

开放系统：SUSE Linux Enterprise Server 12 SP3

Bash 版本：4.3.42(1)-release (x86_64-suse-linux-gnu)

看来您使用的是相当老的 bash RPM 包。请通过

检查安装的RPM

rpm -q bash

最初的 SLES 12 SP3 版本是 4.3-82.1。

更新频道的最新版本是 4.3-83.23.1。此版本解析为

GNU bash，版本 4.3.48(1)-release

请首先确保您拥有有效的订阅和附加的升级存储库，然后运行

zypper -v up bash

顺便说一句，即使你的 bash 包已经过时，你的系统也可能缺少更多的更新，所以运行

zypper -v up

会被推荐。

最后，由于 SLES 12 SP3 不再受支持，请考虑迁移到更新的版本，例如 SLES 12 SP5 或 SLES 15 SP2。
