Sure, I understood that. I'm curious though about the memory consumption of the compression operation, or put in other words: do we need to increase crashkernel reserved memory if we plan to use your gzip approach? It's good to be sure about this, to evaluate the trade-off of core file size vs. necessary reserved memory. Thanks!
