我有一个容器化的 unimrcp 服务器，它作为 kubernetes pod 运行。当我进入容器并做ps -ef它的输出是这样的：

[root@unimrcp-0 fd]# ps -ef
UID        PID  PPID  C STIME TTY          TIME CMD
root         1     0 99 13:13 ?        01:07:38 ./unimrcpserver
root        75     1  0 13:13 ?        00:00:00 [arping] <defunct>
root        76     1  0 13:13 ?        00:00:00 [arping] <defunct>
root       154     0  0 13:14 pts/0    00:00:00 /bin/bash
root       209   154  0 14:21 pts/0    00:00:00 ps -ef

另外，如果我这样做cat /proc/[pid]/fd/1，我会看到一些损坏的输出，如下所示：

未知指令：▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒ ▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒ ▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒ ▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒ ▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒ ▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒ ▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒

为什么进程没有附加控制终端。我已禁用 Unimrcp 记录到标准输出。CPU 利用率也为 99%。有人可以帮忙解决这个问题吗？

这是容器的入口点

#!/bin/sh
source /ip-conf.sh; set_control_media_network "UNIMRCP"
CONTROL_IP=$(get_control_ipv4)
MEDIA_IP=$(get_media_ipv4)
LOG_LEVEL=$(echo $LOG_LEVEL | tr -s " " | xargs)
LOG_OUTPUT=$(echo $LOG_OUTPUT | tr -s " " | xargs)
LOG_HEADERS=$(echo $LOG_HEADERS | tr -s " " | xargs)
sed -i 's+<priority>.*</priority>+''<priority>'$LOG_LEVEL'</priority>+g' 
/usr/local/unimrcp/conf/logger.xml
sed -i 's+<output>.*</output>+''<output>'$LOG_OUTPUT'</output>+g' 
/usr/local/unimrcp/conf/logger.xml
sed -i 's+<headers>.*</headers>+''<headers>'$LOG_HEADERS'</headers>+g' 
/usr/local/unimrcp/conf/logger.xml
sed -i 's+<!-- <ip>.*</ip> -->+''<ip>'$CONTROL_IP'</ip>+g' 
/usr/local/unimrcp/conf/unimrcpserver.xml
sed -i 's+<!-- <rtp-ip>.*</rtp-ip> -->+''<rtp-ip>'$MEDIA_IP'</rtp-ip>+g' 
/usr/local/unimrcp/conf/unimrcpserver.xml 
cd /usr/local/unimrcp/bin/
exec ./unimrcpserver

这是 unimrcp 容器内 /proc/1/fd/ 处 ls -l 的输出
