I've had chromium dump core on me a few times recently (it had run
reliably for a long time before). I'm on a Aug 5 amd64-current and have
chromium-84.0.4147.105p2. My .xsession-errors contains these lines:
[8234:607566400:0817/213026.408392:ERROR:platform_shared_memory_region_posix.cc(250)]
Creating shared memory in /tmp/.org.chromium.Chromium.3srUZ4 failed: Too many
open files (24)
... a few times then
[8234:-980578240:0817/213026.475239:FATAL:platform_channel.cc(148)] Check
failed: . : Too many open files (24)
egdb shows a somewhat bizarre stack trace, so I don't know if it's a
smashed stack or just an unwinding bug:
