2664.0. "EXQUOTA error when DECNET transport is used." by TAV02::GAN () Thu Apr 26 1990 08:31

One of our customers has a DECWINDOWS application (VMS 5.3)
which uses RDB. The application works fine until it is used
in DECNET transport (even in the local station but with
SET DISPLAY/CREATE/NODE=0/TRANSPORT=DECNET). In that case
it fails after a while with the X I/O error followed by a
EXQUOTA error message. It do NOT happens if LOCAL transport
is used or RDB is not used.

I've checked all process quotas, including BYTLM,BIOLM,
ENQLM,PAGEFILEQUOTA etc. Everything is very very high. Looking
from another session using SHOW PROCESS/QUOTA/ID=xxx shows no
remaining quota going down and everything looks fine. Just the
EXQUOTA error continuing...

So I suspected that it is the DECW$SERVER_0 that has quota problem,
I've asked the customer to temporarily modify the DECW$STARTSERVER.COM
and raise the server process BYTLM from 50000 to 200000 and BIOLM
from 60 to 200, and restart the server. Nothing changed.

What can cause that error? Does it come from the server side
or it is an application quota problem? How can it be eliminated?
Any help will be appreciated.

	Thanks in advance

2664.1	EXQUOTA is on the application side	STAR::VATNE	Peter Vatne, VMS Development	`Thu Apr 26 1990 13:59`	5
	Any EXQUOTA errors will be on the application side. The X protocol has no way of transmitting VMS-type errors from the server to the application. Unfortunately, with EXQUOTA errors it really is a guessing game as to which quota is being exceeded.

	Does either the customer's application or RDB disable resource waits? If they are disabled, then it is possible that DECnet would return EXQUOTA during transmission. James
2664.3	I'll check and give here the results.	TAV02::GAN		`Sun Apr 29 1990 03:51`	8
	I'll check if it a resource wait problem. It will take 2 days to get the answer, since it is holiday now. Many thanks for .1 and .2 for their answers. I'll let you know what are the results. Ofer
2664.4	It is ASTLM. But how can it be avoided?	TAV02::GAN		`Wed May 02 1990 10:21`	17
	I've found the cause for that EXQUOTA error message: It was the ASTLIMIT that exhausted. Raising the AST quota from 100 to 3000 seems to eliminate the problem for most of the time. The problem is that the remaining quota of AST is getting eaten very fast, when you move the mouse a lot. That happen even if the application use DECNET transport in the local VAXSTATION. When LOCAL transport is used, the remaining AST quota do not change at all!!! What could be the reason for that AST amount used by DECNET transport, and is there a workaround to avoid it? (even when ASTLM is 3000, moving the mouse for more then 2 minutes continuously causes all AST quota to be eaten and the application crashes with EXQUOTA error). Thanks in advance Ofer Gan
2664.5	Please submit a QAR	STAR::VATNE	Peter Vatne, VMS Development	`Wed May 02 1990 15:00`	3
	Something doesn't sound right here. We fixed the DECwindows transport to use less ASTs in VMS V5.3, not more. I don't know why your ASTs aren't being serviced. I suggest submitting a QAR.

	Are you sure your customer is using VMS V5.3? James
2664.7	It is VMS 5.2	TAV02::GAN		`Thu May 03 1990 02:04`	12
	Sorry that I did not mention it in previous note. The customer is using VMS 5.2. He gave me wrong info on his current version, which I discovered only when I came to his site to find the reason for the EXQUOTA problem. So if it is fixed under VMS 5.3, then I'll advise him to upgrade. Many Mant thanks for your help Ofer Gan
