An application running on ESXi fails. A core file is generated as a result of the crash.
Example
The /sbin/coredump application crashes. The following warning event appears in the vSphere Client:
An application (/sbin/coredump) running on ESXi host has crashed (1 time(s) so far). A core file might have been created at /var/core/coredump-zdump000.
This message appears even if the attempt to write the core file fails due to a storage error.
Impact
Most of the critical applications running on ESXi are automatically restarted. As a result, significant impact is unlikely.
Environment
VMware vSphere ESXi 6.5 VMware vCenter Server 6.0.x VMware vSphere ESXi 5.5 VMware vCenter Server 6.7.x VMware vCenter Server 6.5.x VMware vCenter Server 5.5.x VMware vSphere ESXi 6.0 VMware vSphere ESXi 5.1 VMware vSphere ESXi 5.0 VMware vCenter Server 5.0.x VMware vCenter Server 5.1.x VMware vSphere ESXi 6.7
Resolution
This event warning can be safely ignored. Because critical applications on ESXi are automatically restarted, no additional steps are required to remedy this event.
