I too agree that 3.1 was Very stable and 3.2 for most things seems to be O=
K so
far as I have used it for many things at the ISP I work for. However I hav=
e
come across a reproducable problem with 3.2. just as Sergey has spoken abou=
t,
that does not seem to occur in 3.1.
I am testing the new FreeBSD port of the Inktomi caching server. The size =
of
the processes that are used can grow quite large and are multithreaded.=20
I have found that if I set MAXDSIZ and DFLDSIZ too small (like 512*1024*102=
4) I
can make the server page fault and reboot by making it work hard. (IE make =
the
process grow)
SO far a setting of (2*1024*1024*1024) for both seems to be quite stable u=
nder
.any load, but it seems unsettling that rather than kill a process that is
demanding too much memory, the kernel page faults. Especially since the pro=
cess
runs as a user process not as a system process.
I am no expert on these things, but I welcome the assistance of anyone wil=
ling
to help identify the root of this problem to make FreeBSD more stable. Flam=
es
and put downs about a lack of detail or knowlege like I have seen so far, p=
lease
send to the linux list of choice to save us both some time please. I use
FreeBSD as it is a professional OS with mostly professional people willing =
to
lend a hand.
Thanks
BTW Sergey, I realize that you may be frustrated, however sending messages=
that
are the next best thing to flame bait is not welcome. If you want assistanc=
e,
ask for it. Offline more information can be shared and the outcome shared w=
ith
the list.
