PGAgent:捕获未处理的未知异常;终止
问题描述:
在Postgre DB上不断运行的作业的麻烦,永远不会完成。PGAgent:捕获未处理的未知异常;终止
我曾尝试以下操作来解决它:
- apt-get的更新升级&(PostgreSQL的被更新为最新的)
-
/etc/init.d/postgresql的重新启动
postgresql.service - PostgreSQL RDBMS Loaded: loaded (/lib/systemd/system/postgresql.service; enabled) Active: active (exited) since Fri 2015-10-16 10:06:04 UTC; 9s ago Process: 6787 ExecStart=/bin/true (code=exited, status=0/SUCCESS) Main PID: 6787 (code=exited, status=0/SUCCESS) CGroup: /system.slice/postgresql.service

/etc/init.d/pgagent重启

试图启用pgagent调试模式
vim /etc/default/pgagent
EXTRA_OPTS="-f -l 2 -s /var/log/pgagent hostaddr=localhost dbname=postgres user=postgresext"
- 试图重新启动机器

在
/var/log/pgagent

在
vim /var/log/postgresql/postgresql-9.4-main.log
我只看到:[unknown]@[unknown] LOG: incomplete startup packet LOG: MultiXact member wraparound protections are now enabled LOG: database system is ready to accept connections LOG: autovacuum launcher started [email protected] LOG: could not receive data from client: Connection reset by peer [email protected] LOG: could not receive data from client: Connection reset by peer [email protected] LOG: could not receive data from client: Connection reset by peer [email protected] LOG: could not receive data from client: Connection reset by peer [email protected] LOG: could not receive data from client: Connection reset by peer [email protected] LOG: could not receive data from client: Connection reset by peer [email protected] LOG: could not receive data from client: Connection reset by peer [email protected] LOG: could not receive data from client: Connection reset by peer [email protected] LOG: could not receive data from client: Connection reset by peer [email protected] LOG: could not receive data from client: Connection reset by peer [email protected] LOG: could not receive data from client: Connection reset by peer
我不明白什么是实际问题以及如何解决它实际?
我已经调查一件事是,pgagent[6793]: *** Caught unhandled unknown exception; terminating
可以由不正确的连接终止调用...
答
有点晚来回答这个问题,但我遇到同样的问题,使用pgAgent时,和它造成什么但沮丧。我甚至试图挖掘源代码来解决它,但只是试图让它在我的服务器上编译是一个完全的噩梦,因为它需要的依赖(没有很好的理由)。
因此,考虑到这一点,我决定为Postgres编写一个新的作业调度程序,作为pgAgent的替代品。这叫做jpgAgent,我一直在我的公司使用它几个月,现在没有任何问题。现在我们使用jpgAgent更加稳定,不必担心代理会随机停下来,并且工作不会按照原样运行,因为之前这是一个常见问题。
无论如何,希望它可以帮助你。
