Severity: 1-Blocking


The default location for core files is '/var/core'. On i11000 Series platforms, there is insufficient space in this directory for core files. When a process generates a core file, or when a core file is created manually, the system truncates the core file's content.


Core file content is truncated. Further analysis of the problem that created the core cannot proceed.


-- A process encounters a condition that leads to a core file being generated, or a core file is produced manually. -- Using one of the following platforms: + i11400-DS + i11600 / i11800 + i11600-DS / i11800-DS


Change the location where the kernel places core files. For example, you might use '/appdata' as the destination. Change /proc/sys/kernel/core_pattern to define the pathname used to generate the core file. For more information about core files, refer to the core man page, available by running the following command in tmsh: man core

Fix Information

More space has been made available in '/var/core'. Core files are no longer truncated.
