/proc/sysvipc/shm\n\nThe kernel currently provides no functionality to analyze the RSS and swap\nspace usage of each individual sysvipc shared memory segment.\n\nThis patch adds this info for each existing shm segment by extending the\noutput of /proc/sysvipc/shm by two columns for RSS and swap.\n\nSince shmctl(SHM_INFO) already provides a similiar calculation (it\ncurrently sums up all RSS/swap info for all segments), I did split out a\nstatic function which is now used by the /proc/sysvipc/shm output and\nshmctl(SHM_INFO).\n\nSAP products (esp. the SAP Netweaver ABAP Kernel) uses lots of big shared\nmemory segments (we often have Linux systems with \u003e\u003d 16GB shm usage).\nSometimes we get customer reports about \"slow\" system responses and while\nlooking into their configurations we often find massive swapping activity\non the system. With this patch it\u0027s now easy to see from the command line\nif and which shm segments gets swapped out (and how much) and can more\neasily give recommendations for system tuning. Without the patch it\u0027s\ncurrently not possible to do such shm analysis at all.\n\nAlso...\n\nAdd some spaces in front of the \"size\" field for 64bit kernels to get the\ncolumns correct if you cat the contents of the file.
