https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D210315 --- Comment #14 from commit-hook@freebsd.org --- A commit references this bug: Author: avg Date: Tue Feb 14 13:54:05 UTC 2017 New revision: 313730 URL: https://svnweb.freebsd.org/changeset/base/313730 Log: try to fix RACCT_RSS accounting There could be a race between the vm daemon setting RACCT_RSS based on the vm space and vmspace_exit (called from exit1) resetting RACCT_RSS to zero. In that case we can get a zombie process with non-zero RACCT_RSS. If the process is jailed, that may break accounting for the jail. There could be other consequences. Fix this race in the vm daemon by updating RACCT_RSS only when a process is in the normal state. Also, make accounting a little bit more accurate by refreshing the page resident count after calling vm_pageout_map_deactivate_pages(). Finally, add an assert that the RSS is zero when a process is reaped.
