SUMMARY: xdm problems with ross chips

I got about 4 responses on my origional question:


I'm having a strange problem with xdm. I recently installed two ross mbus
boards for a total of 4 ross cpu's into my SS10 running 4.1.3. Now, xdm
is crashing on my xterms about once every 20 minutes ...

The classic xterms are displaying :

mbuf map full
le0: out of mbufs - packet dropped

I see a patch for this in sunsolve, patch 101894, but it appears to be for
Xterminal v2.0 software and we are running v1.0.

I also noticed that a child xdm process is continually being spawned off from
the parent xdm process. what I mean is a child process will be spawned off
and die and another one will be spawned off immediately. This continues on

I will try to install this patch anyway, but if anyone else can help me out,
I would appreciate it !!!

Thanks ...


After reading the responses, which mainly suggested installing some patches,
I decided to upgrade to SunOS 4.1.4 and v2.0 of the Xterminal software. I
also had a minor configuration glitch with xdm which I solved by reading
the xdm man page and looking at the xdm log file. I needed to create
a Xserver file in my xdm config directory. I have no idea why I didn't need
this file when I was using the hypersparc CPU ...

Anyway I've been running with the Ross quad CPU's for about a week now and
everything seems to be working fine ....

Below are the responses that I received

Thanks !!

Problem Description:

1135605 - An xterminal left idle at the xdm login screen for several days hangs due
to an mbuf leak.

1175423 - Receiving an ethernet giant packet greater than 4096 bytes causes the
xterminal to hang.


I am not sure this will help, but we are running XDM from MIT X11R5 distribution with SunOS 4.1.3, 4.1.3_U1, 4.1.4 without any problems on SS10 with
single Weitek CPU and SS20 with 2 CPUs. Native Openwindows XDM never worked
here (but I didn't try it too hard)..


do you have 101587-01, 101790-01 and 101825-02?
