          Priority: medium
            Bug ID: 83297
          Assignee: wayland-bugs at lists.freedesktop.org
           Summary: weston-terminal: exits under intensive terminal output
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: courmisch at gmail.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: 1.5.0
         Component: weston
           Product: Wayland

While the virtual terminal underneath weston-terminal wants to output a lot of
data really fast, the terminal process may pseudo-randomly exit abruptly.

When this happens, the Weston error console will show something like:

| Error sending request: Resource temporarily unavailable
| child 7795 exited

On my system, this happens about one in two/tree times running "ls -lR /", but
I initially observed the problem with "vlc -vv".

Given the error message, I assume that the Wayland display socket has its
kernel-level buffers saturated in the client-to-server direction, and
libwayland-client exits instead of gracefully handling the transient error due
to non-blocking mode. This is however merely a conjecture.


This bug was originally reported as Debian #760043.
