Bug ID: 278601
Summary: kern.ipc.maxpipekva exhaustion description in
tuning(7)
Product: Documentation
Version: Latest
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: Manual Pages
Assignee: bugs@FreeBSD.org

CC: doc@FreeBSD.org
According to tuning(7), with regard to the kern.ipc.maxpipekva tunable: "This
exhaustion is not fatal; however, and it will only cause pipes to fall back to
using double-copy."
This doesn't seem to be true any longer: pipe(2) fails with ENOMEM, opening
named pipes also fails with ENOMEM, ssh(1) logins fail with "error:
server_accept_loop: pipe(startup_p): Cannot allocate memory", and so on.
