I have noticed, when I open more than 15 chromium instances (windows or tabs), I get the "AW, Snap" error Page:

enter image description here

Seems to me there is some limit how many instances can be running at the same time. I am wondering:

Where does this limit come from?

How can I increase the limit?

I don't see any messages in my logs, indicating that chromium had overstepped some OS-defined limit

I am using Chromium 37.0 on Debian Wheezy

  • delete every file such as ~/.config/chromium/ ~/.cache/chromium/ Then reinstall it. – PersianGulf Mar 6 '15 at 11:22
  • @Mohsen Pahlevanzadeh - this is a new installation (i.e. new profile) of chromium. – Michael Boies Mar 6 '15 at 12:37
  • @wurtel - no, I have checked with free -m and I still have 10GB of free memory. Besides, I can launch additional instances of chrome as a different user on the same machine. – Michael Boies Mar 6 '15 at 12:39
  • Hmm OK, I'm currently typing this into tab 4 of 34 tabs, and I have another window open with 14 tabs open. I am using the google chrome version, though. – wurtel Mar 6 '15 at 12:43

You would not necessarily see error messages in your systems log, when chromium is overstepping some limits.

Try starting chromium from a terminal (rather than clicking on icon), so that you can see any potential error messages in the terminal.

What you are describing seems to be similar to this bugreport. The solution should be to increase the limits (ulimit), specifically the limit of open files (ulimit -n).

  • increasing ulimit for nofile to 8192 fixed the problem for me. Thanks. – Michael Boies Mar 6 '15 at 19:25
