Description

[Naoki Hirata :nhirata (please use needinfo instead of cc)]

Attachment: sample process during semi-hang

I ended up moving my computer from Zombocom to my desk and it switched my network status from on to off and back on again.  Closed a window and the browser hung.

This might be invalid?  Semi-hang = hang like state of unresponsiveness.  After going to lunch and coming back, the browser became responsive again.

Comment 1

[Nicholas Nethercote [inactive]]

This doesn't look like a zombie compartment or a MemShrink bug in general.

Comment 2

[Naoki Hirata :nhirata (please use needinfo instead of cc)]

retitling based on comment 1

Comment 3

[Terrence Cole [:terrence]]

Does this still reproduce?

Comment 4

[Naoki Hirata :nhirata (please use needinfo instead of cc)]

I don't so.  Closing as WFM.  It's hard to tell since I switched computers, upgraded OS, on top of the browser being updated since that time...
