Subject: | bug#43882: 27.1; Gnus sometimes crashes emacs 27.1 during nnir search |
Date: | Tue, 20 Oct 2020 15:11:00 +0200 |
Hi,An update: I started emacs with the increased stack on Monday and have been working as normal since then except that I've been searching for e-mail a bit more often.Today (Thursday), emacs crashed on me again when I was searching for e-mail.Observations:- A few minutes before it started crashing I got a spinning beach ball for a few seconds while composing an e-mail.- The crash took much longer this time. I didn't time it, but maybe in the order of 10-15 minutes.- During this time I observed what I could think of through the Activity monitor:-- Emacs was consuming 100% CPU (of one CPU).-- It was eating memory at a rate of 5 MB every other second-- "Faults" and "UNIX system Calls" increased at a steady rate, but I have no idea where they started from or what is normal behaviour...Now, I am going to reduce the stack size again to force the issue and update to HEAD. Let's see if that makes any difference./MikaelOn Mon, 12 Oct 2020 at 11:45, Robert Pluim <rpluim@gmail.com> wrote:>>>>> On Mon, 12 Oct 2020 09:12:56 +0200, Mikael Svahnberg <Mikael.Svahnberg@bth.se> said:

Why reluctantly? 64M these days is nothing in terms of memory.

You can't, but since you've launched emacs from that shell it will be
ok.
