I resolved as similar problem many years ago it was related to the method o=
f starting then remote display manager. This is an extract from the X termi=
nal installation guide on the thecassandra website. It refers to the start =
command in xstart on the exceed PC. The important thing is the 'exec' comma=
nd in my case it worked without this command but it sometimes left ghost pr=
ocesses and over time it eventually broke the AW. =
6. Use: exec /opt/ia/go_dm as the start command for the DM/Foxview(tm). Use=
rlogin as the preferred connection method. Use the ia account provided wit=
h "remote" as the password.

Dear All, =
=
Following is the complete details of the system and the problem facing AW51=
D =
=
On a power station, there are two AW51D installed with no WP. They are 27AW=
31 and 27AW32. They are running I/A series version 6.1.1 with Display Manag=
er. Both are having similar problems at a regular interval. =
=
Sometimes they just go down on 'panic' signal and sometime their screen fre=
ezes and even remotely we cannot log onto it. Also that machines starts sho=
wing 'Red and Failed' in System Management accessed from the other running =
machine. =
=
The solution to this is to reboot the machine. These machines were running =
fine for two years and after that this problem started coming without any s=
ort of modification in the system. =
=
Both machines are having Additional Display manager licenses and both are a=
ccessed remotely through 'Exceed'. This station is unmanned and so the remo=
te operator controls the plant. =
=
On site they are giving problem. When we removed one machine from site, and=
tested it by powering on in our lab for 10 days, there are no hang ups or =
any other problems. Mind you this machine was tested in a standalone mode w=
ithout connecting to Nodebus. =
=
This led us to assume that something is relate to power problem but we have=
changed power source in the site, still we are having problems. =
=
The details of the 27AW32 machine is as follows and the other machine is id=
entical =
=
AW51D =
Fox P/N : P7560019F181 =
Style/Rev : EB =
S/N : 14550040 =
=
Make : 1999. =
=
It is having 64MB RAM and 8.6 GB Seagate Hard Disk, Processor speed is 360 =
MHz and it is an 'UltraSparc II' machine. =
=
I have checked the disk usage by 'df' command and there is abundance of fre=
e space and there is no disk space issue. =
=
The panic statements on the '/var/adm/messages' on both machines are as des=
cribed in attached 27aw31pa and 27aw32pa files. =
=
The 'vmstat 10 10 ' commands details are given in 27awus and 27aw32us files=
. =
=
The boxes are properly placed with no weight on them. The QF_INFO file for =
27AW32 is in the attached file 27aw32qf. =
=
Can anyone explain what is NVRAM and how can it contribute to such failure =
and how to replace it. =
=
This machine was supplied by Foxboro and no modification in hardware and so=
ftware have been done on it since it arrived. =
=
When I give 'probe-scsi-all' and 'probe-ide' commands on ok prompt in stand=
alone mode no errors are reported. =
=
The output on the 'mpstat 10 10' on both machines are 27aw31mp and 27aw32mp=
files as attached. More over the /etc/hosts and /usr/fox/customer/hi/dmcfg=
files are also attached for 27AW32. =
=
Please read the details and in light of these give your solutions and recom=
mendations. If I need a new box then where can I find the AW51D. Also comme=
nt.

Thanks in advance =
