Chromium is failing with "Too many open files" agian. This bug has been popping up since at least chromium 16. It went away for a while but now its back with a vengeance. I have set fs.file-max to an absurd 50000000 and its still running out of files with about 50 tabs open.

You are likely hitting another ceiling long before you even get to fs.file-max. Try raising nofile in /etc/security/limits.conf. Or ulimit -n.
I did some testing and I believe you are correct, I set -Sn -Hn a bit higher and it appears to function normally again. I guess they only thing for this bug would be to check if these settings should be raised for a default user? Maybe a build warning to raise them?

I just added the following to /etc/security/limits.conf kwhat soft nofile 8192 kwhat hard nofile 10240 I noticed that the memory usage was excessively high for the number of tabs open so either these values need some tuning or they are working around an underlying issue.
