When any program crashes, it dumps core. File name format of the core that gets created can be controlled using sysctl.
One way is: sysctl -w "kernel.core_name_format=/coredumps/%H-%N-%P.core"
%P The Process ID (current->pid)
%U The UID of the process (current->uid)
%N The command name of the process (current->comm)
%H The nodename of the system (system_utsname.nodename)
%% A "%"
