I am running a process (a service) in a container. After few mins the process stops (or a crash) but there is no core dump generated.
When I try to intentionally create a core dump (for E.g: dividing 10/0 in my program) it creates a core dump.
But the same process(without intentional crash) will stop and does not create core dump.
What could be the problem?
Here are more specific details of my kernel
On a VPS:
[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.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
