Hello, I've been using makedumpfile as the crash collector with the -d31 parameter. The machine this is being run on usually have 128-256GB of ram and the resulting crash dumps are in the range of 14-20gb which is very bug for the type of analysis I'm usually performing on crashed machine. I was wondering whether there is a way to further reduce the size and the time to take the dump (now it takes around 25 minutes to collect such a dump). I've seen reports where people with TBs of ram take that long, meaning for a machine with 256gb it should be even faster. I've been running this configuration on kernels 3.12.28 and 4.1 where mmap for the vmcore file is supported. Please advise Regards, Nikolay
