So something can free up the fd's, though I'm not sure of what triggers it.

Shall we do that by default? Anyhow, closing 20 terminals reduced the ll /proc/XXX/fd |wc from 1026 to 850. This is making it extremely difficult to debug. I don't know of a Gnome/Gstreamer/PulseAudio?

We determined that the problem exists in gstreamer, which pidgin cant fix.

In my experience, I believe so.

  1. These pipe handles are specified in the STARTUPINFO structure, which makes them the standard handles inherited by the child process.

Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.

I'd like to monitor this... Sorry for the dumb questions; I haven't been taught processes (aside from fork) or pipes (at all) yet in this class - so I'm not really sure where to start! Comment 7 Behdad Esfahbod 2011-03-29 09:43:21 EDT Looks like there are two issues: - Leak that is already fixed upstream: https://bugzilla.gnome.org/show_bug.cgi?id=632257 - vte generally using too many fds, fedora having a this contact form It sounds like a start of some problem to me. -> Here are my questions: One; how do I use pipes for integers?

Then the scrollback buffer stuff uses three to store three different streams (text stream, attributes stream, and line-breaks stream). If you could try to get the information for the bug as well, that would really help. Once it happened, I was able to capture a screenshot from the output of top. Additional info: It's my guess that the leak comes from a frequent respawn when the ssh command fails.

I know that the pidgin devs need the debugging output from gdb, but other than that I don't know what would be useful, i'm not a dev, just a fanatic user.
