我的Linux CentOS 7（Bacula版本5.2.13）和3个客户端上有一个Bacula服务器。 1是一个Windows和2 Linux（Debian 8和Centos 7）Windows客户端和Debian客户端工作正常，但CentOS客户端有一个问题。 作业失败，错误ERR =中断的系统调用。 看起来，客户端不会在端口9102响应。在这一点上telnet得不到答案，如果我在远程主机上做，但它提供了一个答案，如果我试试它本地。 重新启动后，它将工作一两个小时，直到错误再次出现。
这是我的configuration文件：

而现在有趣的事情。 当我在早上检查bacula.log如果计划的工作工作，它看起来像这样：

作业“Bkp客户端182”不会工作，直到客户端重新启动。 防火墙被禁用。 我把SELinux放在客户端，用ss -lnt |检查端口 grep -i听
LISTEN 0 50 *:9102 *:* LISTEN 0 128 *:22 *:* LISTEN 0 100 127.0.0.1:25 *:* LISTEN 0 128 :::22 :::* LISTEN 0 100 ::1:25 :::*
我重新启动客户端，手动运行这个工作，得到了这个：（运行良好）

更新
我试图重现这种情况，但这次用Redhat 7.3 / 7.2作为客户端，Redhat 7.3作为服务器。 到目前为止他们工作没有任何问题。
更新我监测了CentOS，发现它在工作与不工作之间切换。 Redhat从昨天16:30开始没有问题。
更新和ifconfig -a从客户端的输出

我可以肯定地告诉你：Bacula客户端不需要重新启动。 决不。 所以这个问题来自bacula-fd之下的某个地方。
由于telnet没有答案，bacula正在使用TCP / IP会话，它只是不能工作。 解决networking和/或安全问题，你会解决bacula一个。
