Re: Regular urxvt hangs, Emacs crashes



Is urxvt hanging on startup and consuming 100% cpu? If so, this is probably because of a known kernel bug since 10.5.0.

If not, can you please take a sample (/A/U/Activity Monitor.app) of the urxvt and X11 processes, so I can see where it's hanging.

Hi,

For the last week or two - I can't remember exactly when, but it / might/ coincide with the installation of Security Update 2008-005 - urxvt consoles have been regularly hanging, sometimes after hours of use, sometimes after a few seconds. Emacs also crashes, but less frequently, and it just disappears; it doesn't hang. I hardly use any other X applications so I haven't experienced other crashes.

I have installed urxvt from the rxvt-unicode package in MacPorts. I have been the rxvt-unicode package for over a year and it has not shown any instability before. Since the crashes began, I have updated MacPorts (although I tend to keep reasonably current anyway) and recompiled all dependencies (recursively) of rxvt-unicode, including itself. The frequency of crashing hasn't changed, and has become more frequent if anything. I have also reinstalled X11 2.3.0 a couple of times.

Emacs runs on a Ubuntu guest running on VMWare, and is the standard GTK-enabled Emacs for Ubuntu Hardy. I run it via `ssh -Y ...`.

When the urxvt processes hang, dtruss shows things happening when I move the mouse over the window, but that's where my understanding ends. The window contents are /not/ redrawn, and the mouse cursor becomes completely invisible. The window can be moved and minimized. However, to kill the process, neither SIGINT nor SIGQUIT is enough; SIGABRT or SIGKILL are needed, or a restart of X. I have a couple of SIGABRT crash logs and can forward one or both if they could be useful, or I can generate more.

Is there anything else I can do to try and diagnose these hangs? They seem to happen about 10-20 times per day at the moment, so I should be able to get some useful information quite quickly. They are seriously impeding my ability to work so I'm keen to figure this out.

Thanks, Gavin.
