Summary:
On an old (4.8p10) machine, substantially reducing the pipe size
on a loaded connection causes the system to freeze.
Is this a supported feature?
Did it usd to be broken?
Detail:
[...]
Two days in a row now, just after 6:30, the box freezes, refusing
keyboard input and requiring a reboot.
Queries:
Is this considered an unsupported use of dummynet?
If it should work, was it broken back in 4.8 and, if so, when
was it corrected? I'd rather not take the time up upgrade the
box to 4.11 if I'll then be forced to move to 5.4.
There were changes in dummynet's configuration functions that, among
other things, dealt with protecting certain code sequences with the
proper SPL. They went into the CVS repository after 4.8. I can't tell
whether these fixes would help in your case but you may want to look at
rev. 1.24.2.22 and 1.24.2.25 (RELENG_4) in any case:
