I've run 2 different SBE card in 3 machines. Two of them were identical Intel server MBs with 3GHz Intel CPUs and Kingston RAM. The other was a Biostar MB, Kingston RAM, (and Ultra RAM) and a dual core Pentium 4 (the biostar was just a board we for another computer so I swapped it in as a different set of hardware to check). All of the exhibit the same behaviour they will run under normal load for between a day and a week and then just lock up hard. The Intel setup mentioned was a duplicate of what Brad successfully used on his network.

To aggrevate the problem all I need to do is fire up a popular torrent on an unmetered connection in the office and it will not last a full 24 hours before lock up.

Glad to hear that they do work for some people because I won't feel bad about selling them on ebay then ;)

We use SBE DS-3 cards and have had zero lockups. Currently on MT 2.9.41. Been running with them for about 6 months, knock on wood. We have them on SuperMicro hardware, which tends to be pretty stable. I mention that only in case it is an issue of card and motherboard combination.

Hello Sam,

Curious if both DS3 cards have the lockup problem? You do still have two of them, right? If so, it is unlikely you have two bad DS3 cards. Especially
because if they are the ones you bought from me I know they are good!
<grin>

We never had any trouble with them interfacing our AT&T DS3s. Sure sounds like a hardware issue or possibly MikroTik made a change in their code that now causes this problem. MikroTik has been known to make a change in their
drivers (unknowingly) and render an entire revision of make and model
interface useless.  Happened to us with Intel SC Fiber adapters.

Best,


Brad

Ron, when I was at 2xT1 I was running it through a RB230 without any
issues for BW shaping (only  a couple of queues).  I don't think it is
MT in particular that is the problem.  Could be the specific hardware
that is the issue though.

I am currently running 45MB through a 3.0GHz MT box with an SBE
interface and it handles the bandwidth just fine, although I am having
some locking problems from time to time, but I think they are related to
the sbe DS3 card as opposed to MT itself.

To All,
I have had a good system. I have a 3 Mbps Bonded T1, 100 users. Right now
when I run a speed test to Speakeasy, it starts at 2.6 or2.7 mbps and
quickly windsdown to 15-20 kbps. This is only in the evening and from 7-9AM.
I have a MikroTik in P3 900MHz, w/ 500Mb of ram.
Thisonlyhappens across theMikroTik box.
Any ideas, Mycustopmers are pissed. Some Are threatening to quit.
PLEASE HELP, I'M A DUNCE.
