A couple months ago several people on the bboard posted a complaint about the page faulting bug on the DECstation 3100. Process are swapped out and running (RW) which cases to the machine to go crazy. I was very impressed when someone from DEC searched out my phone number and called me to ask some questions. I am beginning to wonder what has become of this bug. My machine still has to be reboot every couple of days because of it. Has DEC reproduced it, debugged it and fixed it yet? When can we expect a bug fix? Another totally unrelated question How long will it be after X11 release four before DECstation owners get a DECwindows upgrade to X11R4? Is there an upgrade to Fortran?

How long will it be after X11 release four before DECstation owners get a
DECwindows upgrade to X11R4?
Until they do I'll bet that you keep using the Ultrix 3.1 server and
upgrade all of the clients, libraries, header files, etc. assuming
that you stick with the vanilla x11 libraries and don't use any of the
DEC x11 libraries (the dwf stuff I think). That's what I'm doing now
with x11r3.

When can we expect a bug fix? Unfortunately, nothing seems to be fixed yet. We got DEC to lend us 12meg of memory so that our DS3100 would be up to 24meg (fully populated) while they worked on the problem. Since the extra memory was installed, we didn't have a lock up or crash in 45 days. The segmentation faults when trying to start emacs also disappeared. Last week we finally received a patch from DEC claiming that the problem was solved. I installed the patch, removed the extra 12meg, rebooted, and the system locked up twice within a few days. The emacs segmentation faults were also back. Oh well. I called DEC back and now they claim that my system configuration isn't supported: they say I need 16meg for a server instead of 12meg. Ok, fine. I brought it up to 16meg this evening. I have my doubts that this will solve anything because it locked up before with 16meg, although admittedly it was without the patch. I would have let everyone know immediately if the problem had been fixed. Good thing I tested it first. It's no surprise that DEC called you. I sent every article about this that was posted to the person who was handling my bug report. Hope you don't mind, but they claimed they never heard of it before and they were leaning dangerously close to saying that it was something specific to my network and that I had done something wrong. DEC has tried to close my open bug report 4 times now and actually succeeded once because I was on vacation and they talked to someone else. They seem desperate to get the call closed because probably it's beginning to look bad. At any rate, today I had a 5-way conference call with the Ultrix support engineers and customer service. One engineer that I talked to seemed to understand the problem and was genuinely interested in finding a solution. Perhaps I've found the right person to talk to. I'll post if there's anything of interest that comes out of this. -mark University of Pennsylvania Data Communications and Computing Services
