How to obtain application core dump from running process

This document (000019860) is provided subject to the disclaimer at the end of this document.


All SUSE products


A core dump of a process needs to be captured for troubleshooting purposes as the process seems to hang - and no reason or message within the logs.


To attach gdb to a running process run:
$ gdb --pid=<pid>

$ gdb -p <pid>

Within gdb use following commands to create a dump, then detach from running process:
(gdb) gcore
Saved corefile core.<pid>
(gdb) detach



Additional Information

How to provide application cores to support team can be found here:
How to Use getappcore for SUSE Support

 Please also provide a supportconfig of the system when providing a core:
Supportconfig Self Service via SCC/FTP

Note: a corefile is of use only if matching debuginfo is available, means SUSE Support can only accept corefiles from binaries of SUSE products.
