Here's a tidier representation of the list of open files and ports whilst WebKit was not responding: 

http://pastie.textmate.org/117329

And a sample a few moments later: 

http://pastie.textmate.org/117330

[Graham Perrin]

The issue recurred whilst using Firefox so my next guess is that it's an issue with Flash, or with the flashmeeting.open.ac.uk site code. 

I wonder wheether the issue is aggravated by me trying to work through Adobe Flash Player Settings whilst video is broadcasting. 

[Graham Perrin]

Firefox open files and ports, and sample, at time of issue: 

http://pastie.textmate.org/117432 and http://pastie.textmate.org/117433

comparable failure whilst using Firefox

[Graham Perrin]

Ignore comments 4, 5 and 6. They belong with bug 15967. 

I do wish that this Bugzilla would not automatically advance to a different ticket :-(

Thoroughly confused now. 

[David Kilzer (:ddkilzer)]

Thanks for the bug report, Graham.

Could you run "sample Safari 10 10" from a Terminal window when Safari hangs, then post the file (probably written to /tmp/) to this bug?

[Graham Perrin]

Refining this: 

1) http://flashmeeting.open.ac.uk/

2) browsed to the demo
http://flashmeeting.open.ac.uk/fm/flashmeeting.php?pwd=demo-demo

3) as I entered the meeting (and video began) a dialogue (Mac OS?) presented re: Bluetooth audio failure, which is curious because I can't think of *anywhere* where that preference may be set; although I may have preferred a Bluetooth headset at some point, to the best of my knowledge I long ago reverted all preferences to (MacBook Pro) built-in microphone and speakers. 

4) right-click (possibly control-click) the Flash area to present Adobe Flash Player Settings

5) close the settings window immediately without reviewing/changing anything

6) fine so far

7) started/stopped broadcasting once, maybe twice, maybe three times

8) probably set the state to _not_ broadcast before attempting to navigate away 

9) manually truncated the URL to http://flashmeeting.open.ac.uk/

10) keyed (probably) Return

11) according to Dock etc. WebKit was still responding, in fact it stopped responding. 

12) sample Safari 10 10 

I'll attach the sample to this bug. 

---

Factors that may be relevant: 

A) using Saft, 9.x, I can't tell the version from Finder but AFAIR I followed a hint from macosxhints.com to have Saft enable itself in Safari 3.x beta/WebKit.

B) using PithHelmet 2.7 (78). 

C) FLVR present (I purchased it AFAIR at discount prior to 1.0 release) but it's a long time since I tried to use it, it seems I currently have an expired demo present. 

I'll attach a System Profiler report.

Saft and PithHelment are known to cause all kinds of issues.  Please disable/remove them, then try to reproduce this issue.

I'm not sure if FLVR would cause an issue, but it's probably best to remove it to eliminate it as a potential cause.

Will do. 

In the meantime 
http://pastie.textmate.org/118318 shows permissions repaired after upgrading from 10.4.10 to 10.4.11 -- amongst other things,  

> User differs on ./Library/Internet Plug-Ins/Flash Player.plugin/Contents/MacOS, should be 0, owner is 19236

> Permissions differ on ./Library/Internet Plug-Ins/Flash Player.plugin/Contents/MacOS, should be drwxrwxr-x , they are drwxr-xr-x 

but I can't guess whether group writeability would have been a factor. 

[Ian Ragsdale]

I'm seeing a similar issue, and don't have any sort of modifications to Safari installed, although my Flash install is a debug version, not the normal version. 

I haven't been using the site listed in the original report, but I have seen it on Hulu and Youtube. It just started happening since I installed the debug version of flash, and has been happening somewhat regularly. Safari has actually been going into "uninterruptible wait" mode according to ps, and even a kill -9 won't stop it.

[Ahmad Saleem]

Safari and all other browsers don't support Flash plug-in anymore. Can this be closed as "RESOLVED INVALID". Thanks!
