595.0. "ACCVIO from ANALYZE/PROCESS (ANALIMDMP.EXE)" by DRAGNS::SAUNDERS (John Saunders, DECdns Engineering, (508) 275-5424) Wed May 14 1997 14:37

The DNS$SERVER process has been dumping on one of the Easynet name server
systems. When I attempt to analyze the dump on the system which created it, it
access violates.

Now, I'm very familiar with the problems one often has analyzing dumps on
systems other than the system that created the dump, but I don't remember
anything about an access violation. Any ideas?

	OpenVMS version? Platform? Virtual address space? See 875.* and 697.* in VAXAXP::NOTES$ARCHIVE:VMSNOTES_V11 for some previous discussions... Also see the problem report CTI_SRC951016006676.

	Sorry for the lack of detail. OpenVMS VAX V6.2. I'll check those notes. What system is that problem report in? Thanks, John Saunders DECdns Engineering P.S. Here's what I could think of to answer your "virtual memory" question. Is there any other info I should get?

	:I'll check those notes. What system is that problem report in? http://comet.alf.dec.com/ :Here's what I could think of to answer your "virtual memory" question. Is there :any other info I should get? VIRTUALPAGECNT and PGFLQUOTA are the SYSGEN and UAF parameters, and one potentially needs rather large values for analyzing process dumps. ANALYZE/PROCESS does not respond particularly cleanly to insuffient virtual memory, nor to dumps resulting from corrupted stacks.

	RE: .0 Given the failure address, a standard debug session may not work at all. I suggest that you use Delta along with Anal/sys to look at this dump. As Steve H. indicated, analimgdmp does not handle these types of failures well. Dan
595.5	PGFLQUO Increase Worked	DRAGNS::SAUNDERS	John Saunders, DECdns Engineering, (508) 275-5424	`Thu May 15 1997 16:42`	9
	Based on Steve's message, I checked PGFLQUO for my process, found that it was a bit "normal", and increased it. That worked like a charm. I'm curious. I've never used Delta on a process dump. Is that documented somewhere? Do you just define LIB$DEBUG? Thanks, John Saunders DECdns Engineering
595.6		CPEEDY::FLEURY		`Fri May 16 1997 08:32`	7
	RE: .-1 I've had good luck just defining LIB$DEBUG. If the increase in pqflq worked for you that is great!! In the more general case this often does not work. Delta then becomes the only option. Dan
