Hi,
Have a customer that have a couple of Decbridge 9000-MX's crashing
intermittently - see below for the dump information. This is happening
on more than one bridge.
They appear to be running the latest firmware, i.e. V1.2.1.
Any known problems with this version and any fixes.
Below is a copy of the listing from the console of the dumped 900MX.
Any help appreciated.
Thanks,
Steve
CSC Sydney.

| 1237.1 | Looks like a known problem... | NACAD2::KRISHNA | Thu Jul 21 1994 11:35 | 13 | |
There has been some known problems with v1.2.1 of the DECbridge 900MX
firmware. The problems show up if you are using IP fragmentation of
large frames originating at the FDDI interface destined for the
ethernets. We have seen the error you have reported while analyzing
the above problem.
This problem is fixed in the next version v1.3.* (60 day upgrade) of the
DECbridge 900MX firmware, which I believe would be available by the
first week of August or so. If your need is urgent, we do have a fix
for the IP fragmentation problem now (v1.2.2) let me know and we can
work out a way to get the image to you.

| 1237.2 | Bridge crash least of worries. | CGOS01::DMARLOWE | Have you been HUBbed lately? | Thu Jul 21 1994 11:46 | 15 |
On a customer site, we were able to crash a DB 900 in less than
5 minutes. Our problem went beyond that however. After the bridge
repeatedly crashed and came back up several times, the MAM said
enough of this sh*t and went through a reset to factory. That cured
all problems of the bridge crashing as all backplane connections
were toast and there were no more IP packets to fragment so the
bridge never crashed after that. 8^)
Only had to deal with 50 ticked off UNIX users in the geophysical
department. 8^(
Patch works as we are now at 28+ days with no crashes and happy
users.

Krishna, How do we get v1.2.2 of DECbridge 900MX ? Do you want an IPMT raised ? This problem is preventing a network rollout based on these bridges at a large University site. Thanks, Trevor | |||||
