Basically, what does it mean?
Missing separate debuginfo for ... when running gcore
libraries;gdb;core dump
Compilers can be configured to generate extra information with the executable and/or libraries that aid debugging.  With this extra information, your debugger can show the original source code and variable names amongst other things.Unfortunately, this debugging information take up a lot of space on the system.  Considering that they are hardly ever used (if everything is working to plan) then they are just redundant and take up disk space.To get around this, many distros split the package into two - one contains everything that is needed to make that package run and the second contains the debug information above.  The latter are called debuginfo packages and they need to be installed to successfully debug the main package.You're using SuSE and as I don't use it, I can't really comment on how to install these packages on that distro other than I believe you enable a repository and use zypper to install the same package with debuginfo in it's name.On Fedora you enable a repository and use the debuginfo-install command to install these debuginfo package.Your command gcore is creating a core dump of process 56058.  With the debuginfo packages installed it could add far more useful debugging info in the core dump, which is why it's suggesting you install them.
