Hello:
I am running a DS 5500 under Ultrix 4.1. The 5500 was recently
upgraded from a 5400. Since the upgrade I am unable to keep
elcsd running properly for more than a day.
Here is the scenario:
1) reboot
2) write a test syserr message such like this:
eli -f -l "this is test message 1"
uerf show this and the reboot messages correctly.
3) anywhere from 1/2 hour to 1 day later (seems to be dependent
on the load - the more users the quicker the problem comes)
I can no longer write a test syserr message with eli and
I start to see messages like this on the system console:
"Errlog Buffer Full: 221 missed messages"
uerf sometimes shows something like this as the last entry:
********************************* ENTRY 10. *********************************
----- EVENT INFORMATION -----
EVENT CLASS OPERATIONAL EVENT
OS EVENT TYPE 250. ASCII MSG
SEQUENCE NUMBER 123.
OPERATING SYSTEM ULTRIX 32
OCCURRED/LOGGED ON Sat Apr 20 16:12:18 1991 PDT
OCCURRED ON SYSTEM coco
SYSTEM ID x820B1100 HW REV: x0
FW REV: x11
CPU TYPE: R2000A/R3000
PROCESSOR TYPE KN5500
MESSAGE dhu0, line3: recv. fifo overflow
********************************* ENTRY 10. *********************************
4) write another test syserr message like this:
eli -f -l "this is test message 99"
5) I then restart elcsd with "eli -d" followed by "eli -e" .
Messages start to flow again. Now uerf shows the exact message
from step 4) as the last entry, but other messages that were
sent while elcsd was stuck are gone.
I have talked to DEC s/w support but they don't know what is the
problem. On the advice of the DEC s/w support folks I recently
carefully rebuilt my kernel working from the genvmunix kernel and
running doconfig (I usually build things manually) but nothing
seems to have changed.
Does anyone have any ideas?
thanks,
