Getting a core file can sometimes be a bit complicated, and even when properly setup, you might not always get one. This section will explain for various platforms how to properly setup your system to allow it to generate core files.

For all systems, set the proxy.config.stack_dump_enabled config value to 0 in records.config.   It is 1 by default which means that the traffic_server process will grab the SIGSEGV signal and print a stack trace rather than dumping the core.  You must set this configuration variable to 0, so the traffic server process allows the signal to pass on and dump the core.

CONFIG proxy.config.stack_dump_enabled INT 0 

Linux

For an application to be able to generate a core file, it must have write permission to the directory where it should dump the core. This is by default $PWD, and for Traffic Server, this is not a directory that is typically writeable. Therefore, you should tell the kernel to generate core files in a different directory. The following example shows how to tell the system to generate core files like /tmp/core.12345:
