> Then you can view the output data with ms_print or with massif-visualizer. This may help narrow down where in the code we are using the memory. Done! I've dumped the output from ms_print here: http://ix.io/1CrS It seems most of the memory comes from here: 92.78% (998,248,799B) (heap allocation functions) malloc/new/new[], --alloc-fns, etc. ->46.63% (501,656,678B) 0xD38936: ceph::buffer::create_aligned(unsigned int, unsigned int) (in /usr/bin/ceph-osd) | ->45.07% (484,867,174B) 0xDAFED9: AsyncConnection::process() (in /usr/bin/ceph-osd) | | ->45.07% (484,867,174B) 0xC410EB: EventCenter::process_events(int) (in /usr/bin/ceph-osd) | | ->45.07% (484,867,174B) 0xC45210: ???
