elcsd problems

[Rick Fairfield]

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. *********************************

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?
