Bug ID: 271580
Summary: vmemoryuse counts shared memory as a sum for all
processes
Product: Base System
Version: 13.2-STABLE
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: bugs@FreeBSD.org
Reporter: KOT@MATPOCKuH.Ru
The system counts memory uses a summary RSS for every process ran, not
excluding the shared memory.
Resulting, for example, I can't open multiple connections for a postgresql
database in a jail which vmemoryuse is set, because pgsql forks a child
process, that uses a global huge shared memory pool.
