So, what we're seeing is that 1657 ended, but 1941 and 1946 started at the same time, roughly. hence 1941 got the lock and 1946 not. The run of 1657 took less than 20 seconds, so it seems to me 30 seconds are probably fine, but we can go up to a minute.

This issue was first mentioned in bug 1746653. But then I noticed my machine doing it too... This is despite: $ grep . /proc/sys/kernel/core_* /proc/sys/kernel/core_pattern:|/usr/share/apport/apport %p %s %c %d %P /proc/sys/kernel/core_pipe_limit:0 /proc/sys/kernel/core_uses_pid:0 So really there are two problems: 1. ~/core files are created but no /var/crash/ files 2. Because they all have the same name (core_uses_pid == 0), when gnome-shell crashes as a result of an Xwayland crash, you can only get the core from one of them at most.
