1647778 - Tons of zombie "Isolated Web Content Process"es with fission enabled.

Status: RESOLVED DUPLICATE of bug 1626682

(Core :: DOM: Content Processes, defect)

Description

[Emilio Cobos Álvarez (:emilio)]

I've been using Fission for the last couple weeks, and I notice that I can't start up Firefox right after shutting it down.

I end up having to killall firefox firefox-bin, because there's a lot of zombie processes like this:

   5014 ?        Z      1:12 [Isolated Web Co] <defunct>
   5050 ?        Z      0:49 [Isolated Web Co] <defunct>
   5075 ?        Z      0:08 [Isolated Web Co] <defunct>
   5613 ?        Z      0:28 [Isolated Web Co] <defunct>
   5626 ?        Z      0:21 [Isolated Web Co] <defunct>
   5649 ?        Z      0:04 [Isolated Web Co] <defunct>
   5965 ?        Z      0:11 [Isolated Web Co] <defunct>
   6151 ?        Z      0:14 [Isolated Web Co] <defunct>
   6187 ?        Z      0:08 [Isolated Web Co] <defunct>
   6311 ?        Z      0:36 [Isolated Web Co] <defunct>
   7451 ?        Z      0:05 [Isolated Web Co] <defunct>
   7657 ?        Z      0:24 [Isolated Web Co] <defunct>
  11680 ?        Z      0:01 [Isolated Web Co] <defunct>
  12071 ?        Z      0:04 [Isolated Web Co] <defunct>
  12119 ?        Z      0:01 [Isolated Web Co] <defunct

Not sure what the root cause might be, but I'm able to repro this relatively consistently

Emilio, does this seem like a recent regression? Do you have any STR? Can you share your about:support info, in case this is related to any extensions you may have?

Attachment: about:support

I'm afraid I don't have any concrete STR :(

I've also haven't seen this today or yesterday... Have any related changes landed this last couple of days?

Randell thinks this is Linux-only and that this is an updater problem, which may have an IPC bug filed for it already.
