Chrome hangs upon hangup

[Fred Clark]

I have a particular laptop that seems to crash Chrome when I exit a WebRTC video/audio call.  I do a lot of testing of this WebRTC application.  It normally works fine, but when I connect my desktop and my laptop and then try to close, Chrome on the laptop crashes.  At that point there is nothing I can do about it except to wait for about 2 to 3 minutes.  Then it clears itself and all is fine.

Here is a list of devices that I normally use to test with:

1.  HP desktop Windows 10 64 bit.  Very fast and lots of memory.

2. Toshiba laptop  Windows 10 64 bit.  The Problem hardware.

3. Android Asus tablet vs 6.0

4.Samsung S5 phone vs 6.0

5. Surface Pro 3 Windows 10 64 bit

I only have a problem between the HP desktop and the Toshiba laptop and then only the laptop has the problem.  Calls between the laptop and other remote users is also not a problem.  These two PC's are on the same LAN.

I have recently tuned up this laptop and also deleted all extensions from Chrome.  Nothing else on the laptop seems to be a problem.  We have added diagnostics to the application, but it doesn't appear to be an application problem.  It appears to be more of a Chrome issue.  Using Chrome 57.

Any suggestions,

Fred

Can you turn on crash reporting and file a bug with the crash ID? See https://www.chromium.org/for-testers/bug-reporting-guidelines/reporting-crash-bug

Or, is it not actually crashing, but just hanging for 2-3 minutes? In that case maybe the native log would provide some clues.

We had a similar report from a customer of our app crashing chrome 57 when hanging up, but of course can't do this kind of logging on their machine. If you​ find out what it is, please reply here. Thanks!

Best Regards,
Silvia.

Perhaps this is not a crash at all but only hanging.  Sometimes I get a window that appears.  If I right click on it I get "Google Chrome is not responding".  I can then dismiss this tab.  This problem doesn't affect other open tabs, but only the webrtc session closing.  If I go to chrome://crashes, it doesn't show up, so I assume not a crash.  

I will try to figure out "Native logging" and see it that leads anywhere.

Am still having this problem.  It is not crashing, but only hanging.  It seems to hang for 1 to 2 minutes and then clears itself.  While it is hanging I can do nothing with it.  You mention capturing native logs, but I can't seem to get that to work.  Have worked on it with one of our developers, but we get nothing.  Be happy to work with you or someone and show you exactly what it is doing.  It does seem to respond to the close event, but then somewhere in the teardown process it is hanging.  Have also tried with Canary with the same result.

Possibly, a Chrome trace could also help figuring out the problem, see https://www.chromium.org/developers/how-tos/submitting-a-performance-bug. I'd start the trace right before hanging up to make sure nothing interesting is missed.

Hi,

Were you able to figure out the exact issue or maybe any pointers on how to best debug this. I am facing a similar issue in latest versions of chrome where chrome hangs up during ice gathering state for some clients.

Thanks

[fredl...@comcast.net]

No idea, sorry.
