Question

我在容器中运行进程（服务）。几分钟后，进程停止（或崩溃），但没有生成核心转储。

当我尝试有意创建核心转储时（例如，在我的程序中除以10/0），它会创建一个核心转储。

但是相同的过程（没有故意崩溃）将停止并且不会创建核心转储。

可能是什么问题？

以下是我在VPS上的内核的更具体细节：

[root@test101 ~]# sysctl -a |egrep -i "core"
kernel.core_uses_pid = 1
kernel.core_pattern = core.%e.%p
kernel.core_pipe_limit = 4
net.core.somaxconn = 128
net.core.xfrm_aevent_etime = 10
net.core.xfrm_aevent_rseqth = 2
net.core.xfrm_larval_drop = 1
net.core.xfrm_acq_expires = 30
net.core.wmem_max = 131071
net.core.rmem_max = 131071
net.core.wmem_default = 133120
net.core.rmem_default = 133120
net.core.dev_weight = 64
net.core.netdev_max_backlog = 1000
net.core.message_cost = 5
net.core.message_burst = 10
net.core.optmem_max = 20480
net.core.rps_sock_flow_entries = 0
net.core.netdev_budget = 300
net.core.warnings = 1

Answer 1

在/etc/security/limits.conf中添加以下行：

软核无限
硬核无限根软核无限 root hard core unlimited

进程停止而不在OpenVZ Container上创建核心转储
