Bug 18279 – socket(PF_ROUTE) failed: Too many open files

• Component: Page Loading
• Status: RESOLVED INVALID

[Kevin Gale]

I am finding that Safari stops working after a period of time. It will not open any new windows and will not process any links.

When I check the console I see the following:

Apr  2 14:38:52 kevin-gales-computer /Applications/Safari.app/Contents/MacOS/Safari: socket(PF_ROUTE) failed: Too many open files***ntlmRand failed to open /dev/random

It is then followed by errors such as the following:

2008-04-02 14:44:27.091 WebKit[2255] -[BrowserWindowController loadWindow]: failed to load window nib file '/Applications/Safari.app/Contents/Resources/English.lproj/Browser.nib'.

2008-04-02 14:44:27.092 WebKit[2255] Cannot load Interface Builder file '/System/Library/Frameworks/AppKit.framework/Resources/English.lproj/NSAlertPanel.nib'

The only way to solve the problem is to quit Safari (sometimes force quit) and re-launch. This occurs in Safari 3.1 and the WebKit Nightly build I downloaded a few days ago (31388?).

Not sure if this helps but I am currently building a web application so i'm performing alot of HTTP POST's.

Yes, this may be related, as this code sometimes uses temporary files. Could you please attach an output of the following command?

lsof | grep Safari

lsof | grep Safari output 3rd April 2008

This is the current output from Safari as requested. Our DNS is not behaving itself so the 'jonm_laptop.ncs.local' is actually my computer (keving).

Safari was working okay when I ran the command so let me know if you want me to run it the next time Safari stops working.

Yes, output from a non-working Safari would help a lot.

The many closed, but lurking connections make me suspect that the issue is somehow network-related though, and not necessarily a WebKit fault - these all count against the limit of simultaneously open files.

I have attached a file with the requested output from when Safari stops responding.
The console also contained the following:

In the non-working case, there are many more open sockets, so I think that it's indeed a problem with a proxy. Not sure if there is a client-side bug, too, but if there is, it's definitely in lower level OS code, not in WebKit.

Would you be willing to file a bug at <http://bugreport.apple.com> (free registration required) for Apple engineers working on lower levels of network stack to take a look? If not, I can move this bug myself, but there will be less opportunities for them to communicate with you then.

Just had a another crash and I also noticed the following in the console:
ntlmRand failed to open /dev/random

Not sure if this is related or not.

I'll file a bug report and point them at this for more information.

Thank you!

Now closing as INVALID to indicate that this is not a WebKit issue; it will continue to be tracked by Apple internally.
