Okay, now this is getting ridiculous .. and for all those that have been
helping me debug things over the past few days, this isn't a rant against
"people", its a rant against the state of FreeBSD 6.x :(
Its got SERIOUS problems.
As easy as it is to 'blame the hardware', I'm up to my third FreeBSD 6.x
system that is having problems now, all of which ran flawlessly under
FreeBSD 4-STABLE under some serious load ...
And by 'serious load' .. jupiter (the one that was giving me the SegFaults
under those two kernels I tried) was up to 100 vServers running on it
while I was clearning things off of pluto to upgrade her to 6.x ... and
something like 209 days uptime ...
Right now, I have 3 FreeBSD 4.x left in production, and 4 FreeBSD 6.x ...
One 4.x server is running 87 vServers, has been up for 74 days now, and
vmstat 5 shows:
# vmstat 5

2 5 0 3564464 225092 807 0 0 0 505 0 2 4 382 2698 2684 8 9 83
One of my 6.x just went down for the second time today ... locked up solid
... first time it did it today, it was hitting maxpipekva, which seems to
be my biggest headache so far with 6.x ...
Pluto, the one that we've been pretty much fighting over this past
weekend, is running 69 vServers, 1363 processes, a loadavg <1 ... and I'm
lucky to keep it running for 24 hours ...
maxpipekva is set to:
kern.ipc.maxpipekva: 67108864 - kern.ipc.pipekva: 35782656
It just doesn't feel like 6.x is as robust under loaded conditions as
4-STABLE was ... :(
I don't expect anything to get fixed based on this email ... it was more
to get off my chest about those that have been suggesting that I'm
overloading the server(s) and causing the problems ... I loaded them worse
under 4.x, with less problems ... hell, I got better uptimes under load
when I was using unionfs then 6.x right now is giving me *without* any
"funny mounts" :(
